    ABSTRACT The modularization of biosynthetic pathways is a promising approach for enhancing microbial chemical production. We have developed a co-utilization method with glucose and xylose substrates to divide metabolic pathways into distinct production and energy modules to enhance the biosynthesis of para -aminobenzoic acid (pABA) in Escherichia coli . Optimizing initial glucose/xylose concentrations and eliminating carbon leakage resulted in a pABA titer of 8.22 g/L (yield: 0.23 g/g glucose). This strategy was then applied to the biosynthesis of 4APhe, a compound synthesized from chorismate without pyruvate (PYR) release. Utilizing glucose and xylose as co-substrates resulted in the production of 4.90 g/L 4APhe. Although 4APhe production did not benefit from PYR-driven energy generation as pABA production did, high titer was still achieved. This study highlights the effectiveness of modular metabolic pathway division for enhancing the production of key aromatic compounds and provides valuable insight into microbial production of chemicals that require specific biosynthetic donors such as amino groups. IMPORTANCE Microbial biosynthesis of chemicals from renewable resources offers a sustainable alternative to fossil fuel-based production. However, inefficiencies due to substrate diversion into by-products and biomass hinder optimal yields. In this study, we employed a modular metabolic engineering approach, decoupling pathways for chemical production from cell growth. Using glucose and xylose as co-substrates, we achieved the enhancement of p -aminobenzoic acid production in Escherichia coli . Additionally, we demonstrated the versatility of this approach by applying it to the biosynthesis of 4-amino-phenylalanine production. This study highlights the potential of modular metabolic pathway division for increased production of target compounds and provides valuable insight into microbial production of chemicals that require specific biosynthetic donors such as amino groups.

    Cross-coupling reactions between short-lifetime radicals are challenging reactions in organic chemistry. Here, we report the development of an N-heterocyclic carbene (NHC)-mediated radical coupling reaction based on the catalytic machinery of thiamine- and flavin-dependent enzymes. Through a series of enzyme screenings, we found that acetolactate synthase from Thermobispora bispora (TbALS) and its engineered variants exhibit promising catalytic activity toward abiotic radical acylation reactions of α-bromo carbonyl compounds. Notably, the TbALS variant has higher catalytic activity for small nonaromatic substrates despite forming less stable radical intermediates. Furthermore, the catalytic system of TbALS can be applied to photocatalytic reactions utilizing the photoredox properties of FAD. Nonbenzylic alkyl radicals generated from N-acyloxyphthalimides are efficiently converted into the corresponding dialkyl ketones under irradiation of a blue LED. These findings highlight the utility of thiamine- and flavin-dependent enzymes for achieving selective cross-coupling reactions of short-lifetime radicals.

    The demand for the essential commodity chemical 1,2-propanediol (1,2-PDO) is on the rise, as its microbial production has emerged as a promising method for a sustainable chemical supply. However, the reliance of 1,2-PDO production in Escherichia coli on anaerobic conditions, as enhancing cell growth to augment precursor availability remains a substantial challenge. This study presents glucose-based aerobic production of 1,2-PDO, with xylose utilization facilitating cell growth. An engineered strain was constructed capable of exclusively producing 1,2-PDO from glucose while utilizing xylose to support cell growth. This was accomplished by deleting the gloA, eno, eda, sdaA, sdaB, and tdcG genes for 1,2-PDO production from glucose and introducing the Weimberg pathway for cell growth using xylose. Enhanced 1,2-PDO production was achieved via yagF overexpression and disruption of the ghrA gene involved in the 1,2-PDO-competing pathway. The resultant strain, PD72, produced 2.48 ± 0.15 g L-1 1,2-PDO with a 0.27 ± 0.02 g g-1-glucose yield after 72 h cultivation. Overall, this study demonstrates aerobic 1,2-PDO synthesis through the isolation of the 1,2-PDO synthetic pathway from the tricarboxylic acid cycle.

    Previously, we biosynthesized an evolved version of a bio-based polylactide (PLA) on microbial platforms using our engineered lactate-polymerizing enzyme (LPE). This lactate (LA)-based copolyester, LAHB, has advantages over PLA, including improved flexibility and biodegradability, and its properties can be regulated through the LA fraction. To expand the LA-incorporation capacity and improve polymer properties, in the state of in vivo LAHB production, propionyl-CoA transferases (PCTs) that exhibited enhanced production of LA-CoA than the conventional PCTs were selected. Here, the present study has demonstrated that the LA fraction of LAHB could be altered using various PCTs. Enhanced PCT performance was achieved by balancing polymer production and cell growth. Both events are governed by the use of acetyl-CoA, a commonly shared key metabolite. This could be attributed to the different reactivities of individual PCTs towards acetyl-CoA, which serves both as a CoA donor and a leading compound in the TCA cycle. Interestingly, we found complete sequence randomness in the LAHB copolymers, independent of the LA fraction. The mechanism of LA fraction-independent sequence randomness is discussed. This new PCT-based strategy synergistically combines with the evolution of LPE to advance the LAHB project, and enables us to perform advanced applications other than LAHB production utilizing CoA-linked substrates.

    Styrene is an important industrial chemical. Although several studies have reported microbial styrene production, the amount of styrene produced in batch cultures can be increased. In this study, styrene was produced using genetically engineered Escherichia coli. First, we evaluated five types of phenylalanine ammonia lyases (PALs) from Arabidopsis thaliana (AtPAL) and Brachypodium distachyon (BdPAL) for their ability to produce trans-cinnamic acid (Cin), a styrene precursor. AtPAL2-expressing E. coli produced approximately 700 mg/L of Cin and we found that BdPALs could convert Cin into styrene. To assess styrene production, we constructed an E. coli strain that co-expressed AtPAL2 and ferulic acid decarboxylase from Saccharomyces cerevisiae. After a biphasic culture with oleyl alcohol, styrene production and yield from glucose were 3.1 g/L and 26.7% (mol/mol), respectively, which, to the best of our knowledge, are the highest values obtained in batch cultivation. Thus, this strain can be applied to the large-scale industrial production of styrene.

    Nitroaromatic compounds are widely used in industry, but their production is associated with issues such as the hazardousness of the process and low regioselectivity. Here, we successfully demonstrated the production of p-nitrobenzoate (PNBA) from glucose by constructing p-aminobenzoate N-oxygenase AurF-expressing E. coli. We generated this strain, which we named PN-1 by disrupting four genes involved in PNBA degradation: nfsA, nfsB, nemA, and azoR. We then expressed AurF from Streptomyces thioluteus in this strain, which resulted in the production of 945 mg/L PNBA in the presence of 1 g/L p-aminobenzoate. Direct production of PNBA from glucose was achieved by co-expressing the pabA, pabB, and pabC, as well as aurF, resulting in the production of 393 mg/L PNBA from 20 g/L glucose. To improve the PNBA titer, we disrupted genes involved in competing pathways: pheA, tyrA, trpE, pykA, and pykF. The resultant strain PN-4Ap produced 975 mg/L PNBA after 72 h of cultivation. These results highlight the potential of using microorganisms to produce other nitroaromatic compounds.

    AbstractThe C4 unsaturated compound 1,3-butadiene is an important monomer in synthetic rubber and engineering plastic production. However, microorganisms cannot directly produce 1,3-butadiene when glucose is used as a renewable carbon source via biological processes. In this study, we construct an artificial metabolic pathway for 1,3-butadiene production from glucose in Escherichia coli by combining the cis,cis-muconic acid (ccMA)-producing pathway together with tailored ferulic acid decarboxylase mutations. The rational design of the substrate-binding site of the enzyme by computational simulations improves ccMA decarboxylation and thus 1,3-butadiene production. We find that changing dissolved oxygen (DO) levels and controlling the pH are important factors for 1,3-butadiene production. Using DO–stat fed-batch fermentation, we produce 2.13 ± 0.17 g L−1 1,3-butadiene. The results indicate that we can produce unnatural/nonbiological compounds from glucose as a renewable carbon source via a rational enzyme design strategy.

    Microbial metabolic pathway engineering is a potent strategy used worldwide to produce aromatic compounds. We drastically rewired the primary metabolic pathway of Escherichia coli to produce aromatics and their derivatives. The metabolic pathway of E. coli was compartmentalized into the production and energy modules. We focused on the pyruvate-forming reaction in the biosynthesis pathway of some compounds as the reaction connecting those modules. E. coli strains were engineered to show no growth unless pyruvate was synthesized along with the compounds of interest production. Production of salicylate and maleate was demonstrated to confirm our strategy's versatility. In maleate production, the production, yield against the theoretical yield, and production rate reached 12.0 g L-1, 67%, and up to fourfold compared to that in previous reports, respectively; these are the highest values of maleate production in microbes to our knowledge. The results reveal that our strategy strongly promotes the production of aromatics and their derivatives.

    BACKGROUND: The microbial production of useful fuels and chemicals has been widely studied. In several cases, glucose is used as the raw material, and almost all microbes adopt the Embden-Meyerhof (EM) pathway to degrade glucose into compounds of interest. Recently, the Entner-Doudoroff (ED) pathway has been gaining attention as an alternative strategy for microbial production. RESULTS: In the present study, we attempted to apply the ED pathway for isobutanol production in Escherichia coli because of the complete redox balance involved. First, we generated ED pathway-dependent isobutanol-producing E. coli. Thereafter, the inactivation of the genes concerning organic acids as the byproducts was performed to improve the carbon flux to isobutanol from glucose. Finally, the expression of the genes concerning the ED pathway was modified. CONCLUSIONS: The optimized isobutanol-producing E. coli produced 15.0 g/L of isobutanol as the final titer, and the yield from glucose was 0.37 g/g (g-glucose/g-isobutanol).

    Artificial design of metabolic pathways is essential for the production of useful compounds using microbes. Based on this design, heterogeneous genes are introduced into the host, and then various analysis and evaluation methods are conducted to ensure that the target enzyme reactions are functionalized within the cell. In this chapter, we list successful examples of useful compounds produced by designing artificial metabolic pathways, and describe the methods involved in analyzing, evaluating, and optimizing the target enzyme reaction.

    Cellulosomal systems are known as highly efficient biocatalysts in the degradation of lignocellulosic biomass in nature, but they remain unsuitable for industrial applications. In seeking alternatives to natural cellulosomes, casein was chosen as a scaffold for cellulase clustering. Casein is recognized as an excellent substrate for microbial transglutaminase (MTG) because it contains naturally reactive glutamine and lysine residues. A substrate peptide containing an MTG-reactive lysine residue was inserted into the C-terminus of the endoglucanase Cel5A and Cel6A from Thermobifida fusca using genetic engineering. The engineered cellulases, EG(Cel5A) and EG(Cel6A), were conjugated onto casein in different ratios by an MTG-mediated site-specific protein crosslinking reaction. Overall, a more than two-fold increase was observed when EG(Cel5A) was conjugated onto N,N-dimethylcasein, but a small or no change was observed for EG(Cel6A).

    Maleate is one of the most important dicarboxylic acids and is used to produce various polymer compounds and pharmaceuticals. Herein, microbial production of maleate is successfully achieved, to our knowledge for the first time, using genetically modified Escherichia coli. A synthetic pathway of maleate is constructed in E. coli by combining the polyketide biosynthesis pathway and benzene ring cleavage pathway. The metabolic engineering approach used to fine-tune the synthetic pathway drastically improves maleate production and demonstrates that one of the rate limiting steps exists in the conversion of chorismate to gentisate. In a batch culture of the optimised transformant, grown in a 1-L jar fermentor, the amount of produced maleate reaches 7.1 g L-1, and the yield is 0.221 mol mol(-1). Our results suggest that the construction of synthetic pathways by combining a secondary metabolite pathway and the benzene ring cleavage pathway is a powerful tool for producing various valuable chemicals.

    © 2016 American Chemical Society. A novel artificial cellulase was developed by conjugating a DNA aptamer to an endoglucanase catalytic domain, thereby substituting the natural carbohydrate-binding module. Circular dichroism spectroscopy and adsorption isotherm showed the binding motif of cellulose-binding DNA aptamer (CelApt) was G-quadruplex and stem-loop structures stabilized in the presence of salts, and CelApt binding preferred the amorphous region of the solid cellulose. By introducing the revealed salt-switchable cellulose-binding nature of CelApt into a catalytic domain of a cellulase, we created CelApt-catalytic domain conjugate possessing both controllable adsorption on the solid substrates and equal enzymatic activity to the wild-type cellulase. Thus potential use of a responsive DNA aptamer for biocatalysis at a solid surface was demonstrated.

    This journal is © The Royal Society of Chemistry. In biological systems, proteins can form well-organized, higher-order structures with unique functions that would be difficult to achieve with a single protein. These proteinaceous supramolecular structures form by self-assembly, and the spatial arrangement of the protein building blocks in them is very important. In the present study, an artificial system was developed using recombinant proteins as building blocks, which were assembled in a one-dimensional manner. The assembly of these building blocks was based on the avidin-biotin interaction. A tetrameric biotin ligand unit was designed so that the 1:4 stoichiometry of the avidin-biotin interaction was altered to a 1:2 directional interaction between the streptavidin and tetrabiotinylated protein units. In a proof-of-concept study, site-specifically tetrabiotin-labeled endoglucanase and cellulose-binding module units were prepared, and then these components were self-assembled by mixing with streptavidin to mimic a natural cellulosome. The formation of one-dimensional assemblies of the protein units depended on the stoichiometry of the avidin-biotin interaction sites in the system. Interestingly, the saccharification efficiency improved when the component ratio of protein units in the assemblies was changed. The presence of the optimal ratio of the building blocks implies the modularity of the present protein assembly system.

    Recently, the new trend in the second-generation ethanol industry is to use mild pretreatments, in order to reduce costs and to keep higher content of hemicellulose in the biomass. Nevertheless, a high enzyme dosage is still required in the conversion of (hemi)cellulose. The interaction between cellulases and xylanases seems to be an effective alternative to reduce enzyme loading in the saccharification process. At first, to evaluate the synergism of xylanases on bagasse degradation, we have produced two xylanases from glycoside hydrolase family 10 (GH10) and three xylanases from glycoside hydrolase family11 (GH11),from two thermophilic organisms, Thermobifida fusca and Clostridium thermocellum, and one mesophilic organism, Streptomyces lividans. Peracetic acid (PAA) pretreated bagasse was used as substrate. The combination of XynZ-C (GH10, from C. thermocellum), and XlnB (GH11, from S. lividans) presented the highest degree of synergy after 6 h (3,62). However, the combination of XynZ-C and Xyn11A (GH11, from T. fusca) resulted in the highest total yield of reducing sugars. To evaluate the synergism between xylanases and cellulases, commercial cellulase preparation from Trichoderma reesei was combined with the selected xylanases, XynZ-C and Xyn11A. About 2-fold increase was observed in the concentration of reducing sugars, when both xylanases, XynZ-C and Xyn11A, were added together with T. reesei cellulases in the reaction mixture.

    本研究では、持続可能な環境調和型社会の実現に向けて、目的化合物の生産量を向上させることを目的として、高活性な酵素変異体を合理的に開発するための設計戦略の確立を目指す。具体的には、フェニルアラニン脱アンモニア酵素 (PAL) を鋳型酵素として活性測定を行い、分子動力学シミュレーションとの比較から酵素反応速度に関わる要素の抽出とそれに基づいた高活性な変異体設計のためのルール構築を行う。特に現在、酵素と基質の間の親和力を基準として酵素反応速度パラメーターKmを向上させるような研究例は多く行われているものの、反応速度Vmaxについて基準とできる計算値・指標が存在していない。そこで本研究ではVmaxを向上させうる酵素変異体の設計指針を確立させる。 本年度は鋳型酵素PALの酵素変異体モデルを構築し、基質入り口から活性中心に至るまでの時間を算出するためのメソッドの確立を試みた。しかしながら、基質入り口から活性中心に至るまでの途中の地点で最安定となりそれ以上動かなくなってしまう、そもそも計算に時間がかかる等の課題が明らかとなった。計算法に関してはもっと改善する必要性がある。 またそれと並行して、PALの酵素活性中心を除いた部分に変異を導入した酵素変異体群を作成し、活性評価を行った。その結果、野生型と比較して0倍から最大で1.4倍程度の活性を持つPAL変異体のバリエーション獲得に成功した。今度、順次上記計算値と比較する。

    In this study, we aimed to modifiy and extend the substrate specificity of enzymes by deepening our intrinsic understanding. In addition, this study's objective is to establish rational rules for designing enzyme mutants to catalyze enzymatic reactions with high activity. Several types of Information were accumulated by comparing the results of enzyme screening with the constructed enzyme-substrate binding model. The results suggest that the affinity between the enzyme and the substrate is an important factor for the enzyme to be able to recognize the substrate. In fact, it is suggested that the HOT SPOT, which is likely to contribute to increased activity, can be predicted by in silico calculation. Finally, a 2.8-fold increase in activity was achieved with the enzyme mutant compared to the wild type.
