Abstract
Glycosylation is catalyzed by glycosyltransferases using sugar nucleotides or occasionally lipid-linked phosphosugars as donors. However, only very few common sugar nucleotides that occur in humans can be obtained readily, while the majority of sugar nucleotides that exist in bacteria, plants, archaea, or viruses cannot be synthesized in sufficient quantities by either enzymatic or chemical synthesis. The limited availability of such rare sugar nucleotides is one of the major obstacles that has greatly hampered progress in glycoscience. Herein we describe a general cofactor-driven cascade conversion strategy for the efficient synthesis of sugar nucleotides. The described strategy allows the large-scale preparation of rare sugar nucleotides from common sugars in high yields and without the need for tedious purification processes.

Abstract
Regeneration of nicotinamide adenine dinucleotide (NADH) has been the primary interest in the field of enzymatic transformation, especially associating oxidoreductases given the stoichiometric consumption. The synthesized carbene-ligated rhodium complex [(η5-Cp*)Rh(MDI)Cl]+ [Cp* = pentamethylcyclopentadienyl; MDI = 1,1'-methylenebis(3,3'-dimethylimidazolium)] acts as an exceptional catalyst in the reduction of NAD+ to NADH with a turnover frequency of 1730 h-1, which is over twice that of the higher catalytic activity of the commercially available catalyst [Cp*Rh(bpy)Cl]+ (bpy = 2,2'-bipyridine). Offsetting the contentious atmosphere currently taking place over the specific intermediate of the NADH regeneration, this study presents pivotal evidence of a metal hydride intermediate with a bis(carbene) ligand: a stable form of the rhodium hydride intermediate, [(η5-Cp*)Rh(MDI)H]+, was isolated and fully characterized. This enables thorough insight into the possible mechanism and exact intermediate structure in the NAD+ reduction process.

Electrocatalytic CO2 fixation by regenerating reduced cofactor NADH during Calvin Cycle using glassy carbon electrode. PLoS One 2020; 15:e0239340.

Abstract
In this study, an enzymatic pathway has been developed to replicate the Calvin Cycle by creating the individual steps of the carbon cycle in a bioreactor. The technology known as “artificial photosynthesis” converts CO2 emissions into a variety of intermediates that serve as precursors to high-value products. CO2, light, water, and electricity were used as feedstock. An electrochemical reactor was also studied for the regeneration of active NADH operating at constant electrode potential. Initially, a batch electrochemical reactor containing 80 mL of 0.2 mM NAD+ in Tris-buffer (pH 7.40) was used to evaluate the electrode material operating at normal temperature and pressure. The results showed that the cathode is highly electrocatalytically efficient and selective to regenerate 97.45±0.8% of NADH from NAD+ at electrode potential of -2.3 V vs. mercury standard electrode (MSE). The NADH regeneration system was then integrated with ATP regeneration system and bioreactor containing Ribulose bisphosphate carboxylase/oxygenase (RuBisCO). NADH was regenerated successfully during the process electrochemically and then was used by the enzymatic reaction to produce triose phosphate and 3-Phosphoglycerate (3GPA).

Abstract
Enzyme-mediated synthesis of pharmaceutical compounds is a 'green' alternative to traditional synthetic chemistry, and microbial engineering opens up the possibility of using whole cells as mini-factories. Whole-cell biocatalysis reduces cost by eliminating expensive enzyme purification and cofactor addition steps, as well as resulting in increased enzyme stability. Haloferax volcanii is a model halophilic archaeon encoding highly salt and organic solvent tolerant enzymes such as alcohol dehydrogenase (HvADH2), which catalyses the reduction of aldehydes and ketone in the presence of NADPH/NADH cofactor. A H. volcanii strain for constitutive HvADH2 expression was generated using a strong synthetic promoter (p.syn). The strain was immobilised in calcium alginate beads and repeatedly used as a whole-cell biocatalyst. The reduction of acetophenone, used as test substrate, was very successful and high yields were detected from immobilised whole cells over repeated biotransformation cycles. The immobilised H. volcanii retained stability and high product yields after 1 month of storage at room temperature. This newly developed system offers halophilic enzyme expression in its native environment, high product yield, stability and reusability without the addition of any expensive NADPH/NADH cofactor. This is the first report of whole cell-mediated biocatalysis by the halophilic archaeon H. volcanii.

Abstract
A series of water-soluble half-sandwich [Cp*RhIII(N^N)Cl]+ (Cp* = pentamethylcyclopentadiene, N^N-substituted 2,2'-bipyridine) complexes containing electron-donating substituents around the 2,2'-bipyridyl ligand were synthesized and fully characterized for the regioselective reduction of nicotinamide coenzyme (NAD+). The influence of the positional effect of the substituents on the structural, electrochemical, and catalytic properties of the catalyst was systematically studied in detail. The catalytic efficiency of the substituted bipyridine Cp*RhIII complexes are inversely correlated with their redox potentials. The 5,5'-substituted bipyridine Cp*RhIII complex, which had the lowest reduction potential, most effectively regenerated NADH with a turnover frequency of 1100 h-1. Detailed kinetic studies on the generation of intermediate(s) provide valuable mechanistic insight into this catalytic cycle and help to direct the future design strategy of corresponding catalysts.

Abstract
An artificial photosynthesis system coupled with an enzyme was constructed using the nanospherical self-assembly of tyrosyl bolaamphiphiles, which worked as a host matrix exhibiting an antenna effect that allowed enhanced energy transfer to the ZnDPEG photosensitizer. The excited electrons from the photosensitizer were transferred to NAD+ to produce NADH, which subsequently initiated the conversion of an aldehyde to ethanol by alcohol dehydrogenase. Production of NADH and ethanol was enhanced by increasing the concentration of tyrosyl bolaamphiphiles. Spectroscopic investigations proved that the photosensitizer closely associated with the surface of the bolaamphiphile assembly through hydrogen bonds that allowed energy transfer between the host matrix and the photosensitizer. This study demonstrates that the self-assembly of bolaamphiphiles could be applicable to the construction of biomimetic energy systems exploiting biochemical activity.

Abstract
Biodiesel can replace petroleum diesel as it is produced from animal fats and vegetable oils, and it produces about 10 % (w/w) glycerol, which is a promising new industrial microbial carbon, as a major by-product. One of the most potential applications of glycerol is its biotransformation to high value chemicals such as 1,3-propanediol (1,3-PD), dihydroxyacetone (DHA), succinic acid, etc., through microbial fermentation. Glycerol dehydratase, 1,3-propanediol dehydrogenase (1,3-propanediol-oxydoreductase), and glycerol dehydrogenase, which were encoded, respectively, by dhaB, dhaT, and dhaD and with DHA kinase are encompassed by the dha regulon, are the three key enzymes in glycerol bioconversion into 1,3-PD and DHA, and these are discussed in this review article. The summary of the main research direction of these three key enzyme and methods of glycerol bioconversion into 1,3-PD and DHA indicates their potential application in future enzymatic research and industrial production, especially in biodiesel industry.

Abstract
Exiguobacterium sp. F42 was screened as a producer of an enzyme catalyzing the NADPH-dependent stereoselective reduction of ethyl 3-oxo-3-(2-thienyl)propanoate (KEES) to ethyl (S)-3-hydroxy-3-(2-thienyl)propanoate ((S)-HEES). (S)-HEES is a key intermediate for the synthesis of (S)-duloxetine, a potent inhibitor of the serotonin and norepinephrine uptake carriers. The responsible enzyme (KEES reductase) was partially purified, and the gene encoding KEES reductase was cloned and sequenced via an inverse PCR approach. Sequence analysis of the gene for KEES reductase revealed that the enzyme was a member of the short chain dehydrogenase/reductase family. The probable NADPH-interacting site and 3 catalytic residues (Ser-Tyr-Lys) were fully conserved. The gene was highly expressed in Escherichia coli, and the gene product was purified to homogeneity from the recombinant E. coli by simpler procedures than from the original host. The molecular mass of the purified enzyme was 27,500 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and 55,000 as determined by gel filtration chromatography. Our results show that this enzyme can be used for the practical production of (S)-HEES.

Abstract
A novel enantioselective alcohol dehydrogenase, (R)-2-octanol dehydrogenase (PfODH), was discovered among methylotrophic microorganisms. The enzyme was purified from Pichia finlandica and characterized. The molecular mass of the enzyme was estimated to be 83,000 and 30,000 by gel filtration and sodium dodecyl sulfate-polyacrylamide gel electrophoresis, respectively. The enzyme was an NAD(+)-dependent secondary alcohol dehydrogenase and showed a strict enantioselectivity, very broad substrate specificity, and high tolerance to SH reagents. A gene-encoding PfODH was cloned and sequenced. The gene consisted of 765 nucleotides, coding polypeptides of 254 amino acids. The gene was singly expressed and coexpressed together with a formate dehydrogenase as an NADH regenerator in an Escherichia coli. Ethyl (S)-4-chloro-3-hydroxybutanoate and (S)-2-chloro-1-phenylethanol were synthesized using a whole-cell biocatalyst in more than 99 % optical purity.

Abstract
Harvest time: Proflavine drives the reduction of NAD(+) in the presence of a Rh-based electron mediator. Photoregenerated NADH was enzymatically active for oxidation by NADH-dependent L-glutamate dehydrogenase for the synthesis of L-glutamate. This work suggests that proflavine has the potential to become an efficient light-harvesting component in biocatalytic photosynthesis driven by solar energy.

Abstract
Biofilms of Geobacter sulfurreducens were formed under chronoamperometry at -0.5 V and -0.6 V vs. Ag/AgCl on stainless steel cathodes and tested for fumarate reduction. Increasing the surface roughness Ra from 2.0 μm to 4.0 μm increased currents by a factor of 1.6. The overall current density increased with biofilm coverage. When the current density was calculated with respect to the biofilm-coated area only, values up to 280 A/m(2) were derived. These values decreased with biofilm coverage and indicated that isolated cells or small colonies locally provide higher current density than dense colonies. Steel composition affected the current values because of differences in biofilm structure and electron transfer rates. Biofilms formed under polarisation revealed better electrochemical characteristics than biofilm developed at open circuit. This work opens up new guidelines for the design of microbial cathodes: a uniform carpet of isolated bacteria or small colonies should be targeted, avoiding the formation of large colonies.

Abstract
Although there have been a long history of studying and using immobilized enzymes, little has been reported regarding the nature of immobilized cofactors. Herein we report that cofactor NAD(H) covalently attached to silica nanoparticles successfully coordinated with particle-immobilized enzymes and enabled multistep biotransformations. Specifically, silica nanoparticle-attached glutamate dehydrogenase (GLDH), lactate dehydrogenase (LDH) and NAD(H) were prepared and applied to catalyze the coupled reactions for production of alpha-ketoglutarate and lactate with the cofactor regenerated within the reaction cycle. It appeared that particle-particle collision driven by Brownian motion of the nanoparticles provided effective interactions among the catalytic components, and thus realized a dynamic shuttling of the particle-supported cofactor between the two enzymes to keep the reaction cycles continuing. Total turnover numbers (TTNs) as high as 20,000h(-1) were observed for the cofactor. It appeared to us that the use of particle-attached cofactor promises a new biochemical processing strategy for cofactor-dependent biotransformations.

Abstract
Efficient cofactor regeneration and reuse are highly desired for many important biotransformation applications. Here we show for the first time that cofactor NAD(H) covalently attached to micro particles, which can be easily recovered and reused, effectively mediated multistep reactions catalyzed by enzymes that were also immobilized with the micro particles. Such an immobilized enzyme-cofactor catalytic system was examined for the production of methanol from CO(2) with in situ cofactor regeneration. Four enzymes including formate, formaldehyde, alcohol, and glutamate dehydrogenases were coimmobilized using the same particles as that used for cofactor immobilization (enzymes and cofactor were immobilized separately). Reactions were performed by bubbling CO(2) in a suspension solution of the particle-attached enzymes and cofactor. It appeared that the collision among the particles afforded sufficient interactions between the cofactor and enzymes, and thus enabled the sequential transformation of CO(2) to methanol along with cofactor regeneration. For a 30-min batch reaction, a productivity of 0.02 micromol methanol/h/g-enzyme was achieved. That was lower than but comparable to the 0.04 micromol methanol/h/g-enzyme observed for free enzymes and cofactor at the same reaction conditions. The immobilized system showed fairly good stabilities in reusing. Over 80% of their original productivity was retained after 11 reusing cycles, with a cumulative methanol yield based on the amount of cofactor reached 127%. That was a promising enhancement in cofactor utilization as compared to the single-batch yield of 12% observed with free enzymes and free cofactor.

Abstract
Phenylacetaldehyde reductase (PAR) from Rhodococcus sp. ST-10 is useful for chiral alcohol production because of its broad substrate specificity and high stereoselectivity. The conversion of ketones into alcohols by PAR requires the coenzyme NADH. PAR can regenerate NADH by oxidizing additional alcohols, especially 2-propanol. However, substrate conversion by wild-type PAR is suppressed in concentrated 2-propanol. Previously, we developed the Sar268 mutant of PAR, which can convert several substrates in the presence of concentrated 2-propanol. In this paper, further mutational engineering of Sar268 was performed to achieve higher process yield. Each of nine amino acid positions that had been examined for generating Sar268 was subjected to saturation mutagenesis. Two novel substitutions at the 42nd amino acid position increased m-chlorophenacyl chloride (m-CPC) conversion. Moreover, several nucleotide substitutions identified from libraries of random mutations around the start codon also improved the PAR activity. E. coli cells harboring plasmid pHAR1, which has the integrated sequence of the top clones from the above selections, provided greater conversion of m-CPC and ethyl 4-chloro-3-oxobutanoate than the Sar268 mutant, with very high optical purity of products. This mutant is a promising novel biocatalyst for efficient chiral alcohol production.

Abstract
The electrochemical recycling of cofactors during enzymatic biocatalysis has long been
acknowledged as a potentially powerful technology in fine chemical synthesis. Major obstacle for this
approach is that cofactors only in the immediate vicinity of the electrode surface are productive. This
problem further causes high overpotential at electrode surfaces leading to undesired side reactions
producing enzymatically-inactive dimer and isomer of cofactor. So far, several attempts had been
made to address these problems by focusing on surface modifications, which explored to retain the
enzyme and/or cofactor close to the working electrode including electrode deposition and membranes
surrounding the electrode. In this work, we demonstrate a new concept of cofactor regeneration by
using ‘electronically-conductive’ sol-gel hybrid materials. When conductive hybrid gels were added
to the reaction medium, we found that cofactor could be efficiently recycled throughout the whole
reactor system leading to high yield of product, which was unattainable with conventional
technologies.

Abstract
The secondary alcohol dehydrogenase from Thermoanaerobacter ethanolicus 39E (TeSADH) is highly thermostable and solvent-stable, and it is active on a broad range of substrates. These properties make TeSADH an excellent template to engineer an industrial catalyst for chiral chemical synthesis. (S)-1-Phenyl-2-propanol was our target product because it is a precursor to major pharmaceuticals containing secondary alcohol groups. TeSADH has no detectable activity on this alcohol, but it is highly active on 2-butanol. The structural model we used to plan our mutagenesis strategy was based on the substrate's orientation in a horse liver alcohol dehydrogenase*p-bromobenzyl alcohol*NAD(+) ternary complex (PDB entry 1HLD). The W110A TeSADH mutant now uses (S)-1-phenyl-2-propanol, (S)-4-phenyl-2-butanol and the corresponding ketones as substrates. W110A TeSADH's kinetic parameters on these substrates are in the same range as those of TeSADH on 2-butanol, making W110A TeSADH an excellent catalyst. In particular, W110A TeSADH is twice as efficient on benzylacetone as TeSADH is on 2-butanol, and it produces (S)-4-phenyl-2-butanol from benzylacetone with an enantiomeric excess above 99%. W110A TeSADH is optimally active at 87.5 degrees C and remains highly thermostable. W110A TeSADH is active on aryl derivatives of phenylacetone and benzylacetone, making this enzyme a potentially useful catalyst for the chiral synthesis of aryl derivatives of alcohols. As a control in our engineering approach, we used the TbSADH*(S)-2-butanol binary complex (PDB entry 1BXZ) as the template to model a mutation that would make TeSADH active on (S)-1-phenyl-2-propanol. Mutant Y267G TeSADH did not have the substrate specificity predicted in this modeling study. Our results suggest that (S)-2-butanol's orientation in the TbSADH*(S)-2-butanol binary complex does not reflect its orientation in the ternary enzyme-substrate-cofactor complex.

Abstract
The synthesis of diarylmethanols via the reduction of a range of substituted benzophenone and benzoylpyridine derivatives with ketoreductase enzymes (KREDs) has afforded chiral products with high yield (>90%) and ee (up to >99%). Ortho, meta, and para substitutions with a variety of electron-donating, electron-withdrawing, and halogen groups were examined. Substitution at the ortho position and/or highly electronically dissymmetric molecules were not required for good selectivity, as is the case with conventional chemical catalyst reductions.

Abstract
Formate dehydrogenases (FDH) are useful for the regeneration of NADH, which is required for asymmetric reduction by several dehydrogenases and reductases. FDHs have relatively low activity and are labile, especially to alpha-haloketones, thus FDH cannot be applied to the industrial manufacture of optically active alpha-haloalcohols. To stabilize a FDH from Mycobacterium vaccae (McFDH) against the alpha-haloketone ethyl 4-chloroacetoacetate (ECAA), a set of cysteine-mutant enzymes was constructed. Sensitivity to ECAA of mutant C6S was similar to that of the wild-type enzyme, and mutants C249S and C355S showed little activity. In contrast, mutant C256S exhibited remarkable tolerance to ECAA. Surprisingly, mutant C146S was activated by several organic compounds such as ethyl acetate. An optimized mutant, C6A/C146S/C256V (McFDH-26), was obtained by combining several effective mutations. Ethyl (S)-4-chloro-3-hydroxybutanoate [(S)-ECHB] was synthesized from ECAA to 49.9 g/l with an optical purity of more than 99% e.e. using recombinant Escherichia coli cells coexpressing McFDH-26 and a carbonyl reductase (KaCR1) from Kluyveromyces aestuarii.
