Abstract
Sebacic acid (1,10-decanedioic acid) is an important chemical intermediate. Traditional chemical oxidation methods for sebacic acid production do not conform with “green” manufacturing. With the rapid development of enzymatic technologies, a biocatalytic cascade method based on the Baeyer–Villiger monooxygenase was developed. The most attractive point of the method is the oleic acid that can be utilized as raw material, which is abundant in nature. However, this bio-catalysis process needs co-factor electron carriers, and the high cost of the co-factor limits its progress. In this piece of work, a co-factor in situ regeneration system between ADH from Micrococcus luteus WIUJH20 (MlADH) and BVMO is proposed. Since the co-factors of both enzymes are different, switching the co-factor preference of native MlADH from NAD+ to NADP+ is necessary. Switching research was carried out based on in silico simulation, and the sites of Tyr36, Asp 37, Ala38, and Val39 were selected for mutation investigation. The experimental results demonstrated that mutants of MlADH_D37G and MlADH_D37G/A38T/V39K would utilize NADP+ efficiently, and the mutant of MlADH_D37G/A38T/V39K demonstrated the highest sebacic acid yield with the combination of BVMO. The results indicated that the in situ co-factor generation system is successfully developed, which would improve the efficiency of the biocatalytic cascade for sebacic acid production and is helpful for simplifying product isolation, thus, reducing the cost of the enzymatic transformations process.

Abstract
In enzyme engineering, the main targets for enhancing properties are enzyme activity, stereoselective specificity, stability, substrate range, and the development of unique functions. With the advent of genetic code extension technology, non-natural amino acids (nnAAs) are able to be incorporated into proteins in a site-specific or residue-specific manner, which breaks the limit of 20 natural amino acids for protein engineering. Benefitting from this approach, numerous enzymes have been engineered with nnAAs for improved properties or extended functionality. In this review, we focus on applications and strategies for using nnAAs in enzyme engineering. Notably, approaches to computational modelling of enzymes with nnAAs are also addressed. Finally, we discuss the bottlenecks that currently need to be addressed in order to realise the broader prospects of this genetic code extension technique.

Abstract
Isopropanol dehydrogenase (IPADH) is one of the most attractive options for nicotinamide cofactor regeneration due to its low cost and simple downstream processing. However, poor thermostability and strict cofactor dependency hinder its practical application for bioconversions. In this study, we simultaneously improved the thermostability (433-fold) and catalytic activity (3.3-fold) of IPADH from Brucella suis via a flexible segment engineering strategy. Meanwhile, the cofactor preference of IPADH was successfully switched from NAD(H) to NADP(H) by 1.23 × 106-fold. When these variants were employed in three typical bioredox reactions to drive the synthesis of important chiral pharmaceutical building blocks, they outperformed the commonly used cofactor regeneration systems (glucose dehydrogenase [GDH], formate dehydrogenase [FDH], and lactate dehydrogenase [LDH]) with respect to efficiency of cofactor regeneration. Overall, our study provides two promising IPADH variants with complementary cofactor specificities that have great potential for wide applications. IMPORTANCE Oxidoreductases represent one group of the most important biocatalysts for synthesis of various chiral synthons. However, their practical application was hindered by the expensive nicotinamide cofactors used. Isopropanol dehydrogenase (IPADH) is one of the most attractive biocatalysts for nicotinamide cofactor regeneration. However, poor thermostability and strict cofactor dependency hinder its practical application. In this work, the thermostability and catalytic activity of an IPADH were simultaneously improved via a flexible segment engineering strategy. Meanwhile, the cofactor preference of IPADH was successfully switched from NAD(H) to NADP(H). The resultant variants show great potential for regeneration of nicotinamide cofactors, and the engineering strategy might serve as a useful approach for future engineering of other oxidoreductases.

Abstract
Abstract
Pfizer and the Medicines Patent Pool (MPP) have reached a voluntary licensing agreement for Paxlovid (nirmatrelvir+ritonavir), a novel antiviral for COVID-19 taken orally in the first 5 days from symptom onset. The Pfizer-MPP deal enables 95 low- and middle-income countries (L/MICs) to access affordable biosimilars. Generics are delayed awaiting bioequivalence testing, and may be ineffective in L/MICs with reduced testing capacity, which comprise only 10% of global diagnoses. 39% of diagnoses originate in MICs forced to pay high prices due to exclusion from the Pfizer-MPP deal. Cost-effectiveness of Paxlovid could be limited compared to the creation of sustainable vaccine infrastructure in these nations, delaying socioeconomic pandemic recovery. Furthermore, Paxlovid may not be cost-effective in vaccinated populations and concerns remain over ritonavir drug interactions with COVID-19 comorbidity medications. We call for expanded coverage by the Paxlovid-MPP deal, greater access to testing.

Abstract
In recent years, CO2 reduction and utilization have been proposed as an innovative solution for global warming and the ever-growing energy and raw material demands. In contrast to various classical methods, including chemical, electrochemical, and photochemical methods, enzymatic methods offer a green and sustainable option for CO2 conversion. In addition, enzymatic hydrogenation of CO2 into platform chemicals could be used to produce economically useful hydrogen storage materials, making it a win-win strategy. The thermodynamic and kinetic stability of the CO2 molecule makes its utilization a challenging task. However, Nicotine adenine dinucleotide (NAD+)-dependent formate dehydrogenases (FDHs), which have high selectivity and specificity, are attractive catalysts to overcome this issue and convert CO2 into fuels and renewable chemicals. It is necessary to improve the stability, cofactor necessity, and CO2 conversion efficiency of these enzymes, such as by combining them with appropriate hybrid systems. However, metal-independent, NAD+-dependent FDHs, and their CO2 reduction activity have received limited attention to date. This review outlines the CO2 reduction ability of these enzymes as well as their properties, reaction mechanisms, immobilization strategies, and integration with electrochemical and photochemical systems for the production of formic acid or formate. The biotechnological applications of FDH, future perspectives, barriers to CO2 reduction with FDH, and aspects that must be further developed are briefly summarized. We propose that constructing hybrid systems that include NAD+-dependent FDHs is a promising approach to convert CO2 and strengthen the sustainable carbon bio-economy.

Abstract
L-tert-leucine (L-Tle) is widely used as vital chiral intermediate for pharmaceuticals and as chiral auxiliarie for organocatalysis. L-Tle is generally prepared via the asymmetric reduction of trimethylpyruvate (TMP) catalyzed by NAD+-dependent leucine dehydrogenase (LeuDH). To improve the catalytic efficiency and coenzyme affinity of LeuDH from Bacillus cereus, mutation libraries constructed by error-prone PCR and iterative saturation mutation were screened by two kinds of high-throughput methods. Compared with the wild type, the affinity of the selected mutant E24V/E116V for TMP and NADH increased by 7.7- and 2.8-fold, respectively. And the kcat/Km of E24V/E116V on TMP was 5.4-fold higher than that of the wild type. A coupled reaction comprising LeuDH with glucose dehydrogenase of Bacillus amyloliquefaciens resulted in substrate inhibition at high TMP concentrations (0.5 M), which was overcome by batch-feeding of the TMP substrate. The total turnover number and specific space-time conversion of 0.57 M substrate increased to 11,400 and 22.8 mmol·h-1·L-1·g-1, respectively. KEY POINTS: • The constructed new high-throughput screening strategy takes into account the two indicators of catalytic efficiency and coenzyme affinity. • A more efficient leucine dehydrogenase (LeuDH) mutant (E24V/E116V) was identified. • E24V/E116V has potential for the industrial synthesis of L-tert-leucine.

Abstract
Reductions play a key role in organic synthesis, producing chiral products with new functionalities. Enzymes can catalyse such reactions with exquisite stereo-, regio- and chemoselectivity, leading the way to alternative shorter classical synthetic routes towards not only high-added-value compounds but also bulk chemicals. In this review we describe the synthetic state-of-the-art and potential of enzymes that catalyse reductions, ranging from carbonyl, enone and aromatic reductions to reductive aminations.

Abstract
An electrochemically driven nicotinamide recycling system, referred to as the 'electrochemical leaf' has unique attributes that may suit it to the small-scale industrial synthesis of high-value chemicals. A complete enzyme cascade can be immobilized within the channels of a nanoporous electrode, allowing complex reactions to be energized, controlled and monitored continuously in real time. The electrode is easily prepared by depositing commercially available indium tin oxide (ITO) nanoparticles on a Ti support, resulting in a network of nanopores into which enzymes enter and bind. One of the enzymes is the photosynthetic flavoenzyme, ferredoxin NADP+ reductase (FNR), which catalyzes the quasi-reversible electrochemical recycling of NADP(H) and serves as the transducer. The second enzyme is any NADP(H)-dependent dehydrogenase of choice, and further enzymes can be added to build elaborate cascades that are driven in either oxidation or reduction directions through the rapid recycling of NADP(H) within the pores. In this Article, we describe the measurement of key enzyme/cofactor parameters and an essentially linear scale-up from an analytical scale 4 mL reactor with a 14 cm2 electrode to a 500 mL reactor with a 500 cm2 electrode. We discuss the advantages (energization, continuous monitoring that can be linked to a computer, natural enzyme immobilization, low costs of electrodes and low cofactor requirements) and challenges to be addressed (optimizing minimal use of enzyme applied to the electrode).

Abstract
Formate dehydrogenases are critical tools for nicotinamide cofactor regeneration, but their limited catalytic efficiency (kcat/Km) is a major drawback. A formate dehydrogenase from Burkholderia stabilis 15516 (BstFDH) was the first native NADP+-dependent formate dehydrogenase reported and has the highest kcat/Km toward NADP+ (kcat/KmNADP+) compared with other FDHs that can utilize NADP+ as a hydrogen acceptor. However, the substrate and cofactor affinities of BstFDH are inferior to those of other FDHs, making its practical application difficult. Herein, we engineered recombinant BstFDH to enhance its HCOO- and NADP+ affinities. Based on sequence information analysis and homologous modeling results, I124, G146, S262, and A287 were found to affect the binding affinity for HCOO- and NADP+. By combining these mutations, we identified a BstFDH variant (G146M/A287G) that reduced KmNADP+ to 0.09 mM, with a concomitant decrease in KmHCOO-, and gave 1.6-fold higher kcat/KmNADP+ than the wild type (WT). Furthermore, BstFDH I124V/G146H/A287G, with the lowest KmHCOO- of 8.51 mM, showed a catalytic efficiency that was 2.3-fold higher than that of the wild type and a decreased KmNADP+ of 0.11 mM. These results are beneficial for improving the performance of NADP+-dependent formate dehydrogenase in the NADPH regeneration of various bioreductive reactions and provide a useful guide for engineering of the substrate and cofactor affinity of other enzymes.

Abstract
Among many genes encoding for amino acid dehydrogenase, a novel leucine dehydrogenase gene from Exiguobacterium sibiricum (EsiLeuDH) was isolated by using genome mining strategy. EsiLeuDH was overexpressed in Escherichia coli BL21 (DE3), followed by purification and characterization. The high thermostability of the enzyme confers its half-life up to 14.7 h at 50°C. Furthermore, the substrate specificity shows a broad spectrum, including many L-amino acids and aliphatic α-keto acids, especially some aryl α-keto acids. This enzyme coupled with recombinant formate dehydrogenase (FDH) was used to catalyze trimethylpyruvic acid (TMP) through reductive amination to generate enantiopure L-tert-leucine (L-Tle). In order to overcome the substrate inhibition effect, a fed-batch feeding strategy was adopted to transform up to 0.8 M of TMP to L-Tle, with an average conversion rate of 81% and L-Tle concentration of 65.6 g⋅L–1. This study provides a highly efficient biocatalyst for the synthesis of L-Tle and lays the foundation for large-scale production and application of chiral non-natural amino acids.

Abstract
Nowadays, the use of formate dehydrogenase (FDH, EC 1.17.1.9) is well established as a means of NADH regeneration from NAD+ via the coupled conversion of formate into carbon dioxide. Recent studies have been reported that specifically Chaetomium thermophilum FDH (CtFDH) is the most efficient FDH catalyzing this reaction in reverse (i.e. using CO2 as a substrate to produce formate, and thereby regenerating NAD+). However, to date the production of active CtFDH at high protein expression levels has received relatively little attention. In this study, we have tested the effect of batch and high cell density fermentation (HCDF) strategies in a small stirred fermenter, as well as the effect of supplementing the medium with casamino acids, on the expressed level of secreted CtFDH using P. pastoris. We have established that the amount of expressed CtFDH was indeed enhanced via a HCDF strategy and that extracellular protease activity was eliminated via the addition of casamino acids into the fermentation medium. On this basis, secreted CtFDH in an active form can be easily separated from the fermentation and can be used for subsequent biotechnological applications.

Abstract
Porous graphitic carbon is a versatile stationary phase for high-performance liquid chromatography which performs especially well for isomeric separations. Shape-sensitivity of the stationary phase is caused by a steric effect when a molecule interacts with a flat carbon surface. It follows that branched, non-flat molecules are eluted much earlier than flat or linear molecules. In this short communication we show that if a molecule has a highly ionizable group, the "shape" of a molecule part which is farther from the ionizable group affects retention much more than the "shape" of a molecule part which is closer to the ionizable group. Dipeptides which consist of tert-leucine and norleucine were used as an example. Basic and acidic eluents were used. Retention strongly depends on whether a norleucine or tert-leucine residual is located near the non-ionized side in an eluent for both basic and acidic eluents. A residual located on the opposite side is less important. To investigate the possible causes of this peculiar retention behavior we compared the retention behavior of these dipeptides for porous graphitic carbon with the behavior for other types of stationary phases and with the calculated physicochemical properties. Strong and complex dependence of elution order on a mobile phase composition is demonstrated. The separation of other dileucine isomers is also considered. The applicability of porous graphitic carbon for the separation of complex mixtures of isomeric peptides is discussed.

Abstract
We have employed computational approaches-FireProt and FRESCO-to predict thermostable variants of the reductase component (C1 ) of (4-hydroxyphenyl)acetate 3-hydroxylase. With the additional aid of experimental results, two C1 variants, A166L and A58P, were identified as thermotolerant enzymes, with thermostability improvements of 2.6-5.6 °C and increased catalytic efficiency of 2- to 3.5-fold. After heat treatment at 45 °C, both of the thermostable C1 variants remain active and generate reduced flavin mononucleotide (FMNH- ) for reactions catalyzed by bacterial luciferase and by the monooxygenase C2 more efficiently than the wild type (WT). In addition to thermotolerance, the A166L and A58P variants also exhibited solvent tolerance. Molecular dynamics (MD) simulations (6 ns) at 300-500 K indicated that mutation of A166 to L and of A58 to P resulted in structural changes with increased stabilization of hydrophobic interactions, and thus in improved thermostability. Our findings demonstrated that improvements in the thermostability of C1 enzyme can lead to broad-spectrum uses of C1 as a redox biocatalyst for future industrial applications.

Abstract
An engineered metabolic pathway consisting of reactions that convert fatty acids to aldehydes and eventually alkanes would provide a means to produce biofuels from renewable energy sources. The enzyme aldehyde-deformylating oxygenase (ADO) catalyzes the conversion of aldehydes and oxygen to alkanes and formic acid and uses oxygen and a cellular reductant such as ferredoxin (Fd) as co-substrates. In this report, we aimed to increase ADO-mediated alkane production by converting an unused by-product, formate, to a reductant that can be used by ADO. We achieved this by including the gene (fdh), encoding formate dehydrogenase from Xanthobacter sp. 91 (XaFDH), into a metabolic pathway expressed in Escherichia coli Using this approach, we could increase bacterial alkane production, resulting in a conversion yield of ∼50%, the highest yield reported to date. Measuring intracellular nicotinamide concentrations, we found that E. coli cells harboring XaFDH have a significantly higher concentration of NADH and a higher NADH/NAD+ ratio than E. coli cells lacking XaFDH. In vitro analysis disclosed that ferredoxin (flavodoxin):NADP+ oxidoreductase could use NADH to reduce Fd and thus facilitate ADO-mediated alkane production. As formic acid can decrease the cellular pH, the addition of formate dehydrogenase could also maintain the cellular pH in the neutral range, which is more suitable for alkane production. We conclude that this simple, dual-pronged approach of increasing NAD(P)H and removing extra formic acid is efficient for increasing the production of renewable alkanes via synthetic biology-based approaches.

Abstract
An increasing number of biocatalytic oxidation reactions rely on H2 O2 as a clean oxidant. The poor robustness of most enzymes towards H2 O2 , however, necessitates more efficient systems for in situ H2 O2 generation. In analogy to the well-known formate dehydrogenase to promote NADH-dependent reactions, we here propose employing formate oxidase (FOx) to promote H2 O2 -dependent enzymatic oxidation reactions. Even under non-optimised conditions, high turnover numbers for coupled FOx/peroxygenase catalysis were achieved.

Abstract
Oxidative damage is among the factors associated with the onset of chronic pathologies, such as neurodegenerative and metabolic diseases. Several classes of anti-oxidant compounds have been suggested as having a protective role against cellular stressors, but, in this perspective, peptides’ world represents a poorly explored source. In the present study, the free radical scavenging properties, the metal ion reducing power, and the metal chelating activity of a series of sulfurated amino acids and tripeptides were determined in vitro through canonical assays (DPPH, ABTS, CUPRAC, FRAP, PM, and EECC) and estimated in comparison with the corresponding activities of synthetic peptide semicarbazones, incorporating the peculiar non-proteinogenic amino acid, tert-leucine (tLeu). The compounds exhibited remarkable anti-oxidant properties. As expected, sulfurated compounds 1–5 were found to be the most efficient radical scavengers and strongest reductants. Nevertheless, tLeu-containing peptides 7 and 8 disclosed notable metal reducing and chelating activities. These unprecedented results indicate that tLeu-featuring di- and tripeptide backbones, bearing the semicarbazone chelating moiety, are compatible with the emergence of an anti-oxidant potential. Additionally, when tested against a panel of enzymes usually targeted for therapeutic purposes in neurodegenerative and metabolic disorders, all samples were found to be good inhibitors of tyrosinase.

Abstract
The Ehrlich pathway is a major route for the renewable production of higher alcohols. However, the product scope of the Ehrlich pathway is restricted, and the product selectivity is suboptimal. Here, we demonstrate that a Coenzyme A (CoA) detour, which involves conversion of the 2-keto acids into acyl-CoAs, expands the biological toolkit of reaction chemistries available in the Ehrlich pathway to include the gamut of CoA-dependent enzymes. As a proof-of-concept, we demonstrated the first biosynthesis of a tertiary branched-alcohol, pivalcohol, at a level of ∼10 mg/L from glucose in Escherichia coli, using a pivalyl-CoA mutase from Xanthobacter autotrophicus. Furthermore, engineering an enzyme in the CoA detour, the Lactobacillus brevis CoA-acylating aldehyde dehydrogenase, allowed stringent product selectivity. Targeted production of 3-methyl-1-butanol (3-MB) in E. coli mediated by the CoA detour showed a 3-MB:side-product (isobutanol) ratio of >20, an increase over the ratios previously achieved using the conventional Ehrlich pathway.

Abstract
The origin of the catalytic power of enzymes has been a question of debate for a long time. In this regard, the possible contribution of protein dynamics in enzymatic catalysis has become one of the most controversial topics. In the present work, the hydride transfer step in the formate dehydrogenase (FDH EC 1.2.1.2) enzyme is studied by means of molecular dynamic (MD) simulations with quantum mechanics/molecular mechanics (QM/MM) potentials in order to explore any correlation between dynamics, tunnelling effects and the rate constant. The temperature dependence of the kinetic isotope effects (KIEs), which is one of the few tests that can be studied by experiments and simulations to shed light on this debate, has been computed and the results have been compared with previous experimental data. The classical mechanical free energy barrier and the number of recrossing trajectories seem to be temperature-independent while the quantum vibrational corrections and the tunnelling effects are slightly temperature-dependent over the interval of 5-45 °C. The computed primary KIEs are in very good agreement with previous experimental data, being almost temperature-independent within the standard deviations. The modest dependence on the temperature is due to just the quantum vibrational correction contribution. These results, together with the analysis of the evolution of the collective variables such as the electrostatic potential or the electric field created by the protein on the key atoms involved in the reaction, confirm that while the protein is well preorganised, some changes take place along the reaction that favour the hydride transfer and the product release. Coordinates defining these movements are, in fact, part of the real reaction coordinate.

Abstract
Asymmetric reductive aminations are some of the most important reactions in the preparation of active pharmaceuticals, as chiral amines feature in many of the world's most important drugs. Although many enzymes have been applied to the synthesis of chiral amines, the development of reductive amination reactions that use enzymes is attractive, as it would permit the one-step transformation of readily available prochiral ketones into chiral amines of high optical purity. However, as most natural "reductive aminase" activities operate on keto acids, and many are able to use only ammonia as the amine donor, there is considerable scope for the engineering of natural enzymes for the reductive amination of ketones, and also for the preparation of secondary amines using alkylamines as donors. This review summarises research into the development of NAD(P)H-dependent dehydrogenases for the reductive amination of ketones, including amino acid dehydrogenases (AADHs), natural amine dehydrogenases (AmDHs), opine dehydrogenases (OpDHs) and imine reductases (IREDs). In each case knowledge of the structure and mechanism of the enzyme class is addressed, with a further description of the engineering of those enzymes for the reductive amination of ketones towards primary and also secondary amine products.

Abstract
This study reports the application of peptide linker in the construction of bi-functional formate dehydrogenase (FDH) and leucine dehydrogenase (LeuDH) enzymatic complex for efficient cofactor regeneration and L-tert leucine (L-tle) biotransformation. Seven FDH-LeuDH fusion enzymes with different peptide linker were successfully developed and displayed both parental enzyme activities. The incorporation order of FDH and LeuDH was investigated by predicting three-dimensional structures of LeuDH-FDH and FDH-LeuDH models using the I-TASSER server. The enzymatic characterization showed that insertion of rigid peptide linker obtained better activity and thermal stability in comparison with flexible peptide linker. The production rate of fusion enzymatic complex with suitable flexible peptide linker was increased by 1.2 times compared with free enzyme mixture. Moreover, structural analysis of FDH and LeuDH suggested the secondary structure of the N-, C-terminal domain and their relative positions to functional domains was also greatly relevant to the catalytic properties of the fusion enzymatic complex. The results show that rigid peptide linker could ensure the independent folding of moieties and stabilized enzyme structure, while the flexible peptide linker was likely to bring enzyme moieties in close proximity for superior cofactor channeling.

Abstract
NAD+-dependent formate dehydrogenase (FDH; EC 1.2.1.2) is an industrial enzyme widely used for NADH regeneration. However, enzyme inactivation caused by the oxidation of cysteine residues is a flaw of native FDH. In this study, we relieved the oxidation of the free cysteine of FDH from Candida boidinii (CboFDH) through the construction of disulfide bonds between A10 and C23 as well as I239 and C262. Variants A10C, I239C, and A10C/I239C were obtained by the site-directed mutagenesis and their properties were studied. Results showed that there were no significant changes in the optimum temperature and pH between variants and wild-type CboFDH. However, the stabilities of all variant enzymes were improved. Specifically, the CboFDH variant A10C (A10Cfdh) showed a significant increase in copper ion resistance and acid resistance, a 6.7-fold increase in half-life at 60°C, and a 1.4-fold increase in catalytic efficiency compared with the wild type. Asymmetric synthesis of l-tert-leucine indicated that the process time was reduced by 40% with variant A10Cfdh, which benefited from the increase in catalytic efficiency. Circular dichroism analysis and molecular dynamics simulation indicated that variants that contained disulfide bonds lowered the overall root mean square deviation (RMSD) and consequently increased the protein rigidity without affecting the secondary structure of enzyme. This work is expected to provide a viable strategy to avoid the microbial enzyme inactivation caused by the oxidation of the free cysteine residues and improving their performances. IMPORTANCE FDH is widely used for NADH regeneration in dehydrogenase-based synthesis of optically active compounds to decrease the cost of production. This study highlighted a viable strategy that was used to eliminate the oxidation of free cysteine residues of FDH from Candida boidinii by the introduction of disulfide bonds. Using this strategy, we obtained a variant FDH with improved activity and stability. The improvement of activity and stability of FDH is expected to reduce its price and then further to decrease the cost of its application.

Abstract
Systems that can regulate and coordinate the expression of multiple enzymes for metabolic regulation and synthesis of important drug intermediates are poorly explored. In this work, a strategy for constructing a tunable multi-enzyme-coordinate expression system for biosynthesis of chiral drug intermediates was developed and evaluated by connecting protein-protein expressions, regulating the strength of ribosome binding sites (RBS) and detecting the system capacity for producing chiral amino acid. Results demonstrated that the dual-enzyme system had good enantioselectivity, low cost, high stability, high conversion rate and approximately 100% substrate conversion. This study has paved a new way of exploring metabolic mechanism of functional genes and engineering whole cell-catalysts for synthesis of chiral α-hydroxy acids or chiral amino acids.

Structural basis for double cofactor specificity in a new formate dehydrogenase from the acidobacterium Granulicella mallensis MP5ACTX8. Appl Microbiol Biotechnol 2015; 99:9541-54.

Abstract
Formate dehydrogenases (FDHs) are considered particularly useful enzymes in biocatalysis when the regeneration of the cofactor NAD(P)H is required, that is, in chiral synthesis with dehydrogenases. Their utilization is however limited to the recycling of NAD(+), since all (apart one) of the FDHs characterized so far are strictly specific for this cofactor, and this is a major drawback for their otherwise wide applicability. Despite the many attempts performed to modify cofactor specificity by protein engineering different NAD(+)-dependent FDHs, in the general practice, glucose or phosphite dehydrogenases are chosen for the recycling of NADP(+). We report on the functional and structural characterization of a new FDH, GraFDH, identified by mining the genome of the extremophile prokaryote Granulicella mallensis MP5ACTX8. The new enzyme displays a valuable stability in the presence of many organic cosolvents as well as double cofactor specificity, with NADP(+) preferred over NAD(+) at acidic pH values, at which it also shows the highest stability. The quite low affinities for both cofactors as well as for the substrate formate indicate, however, that the native enzyme requires optimization to be applied as biocatalytic tool. We also determined the crystal structure of GraFDH both as apoprotein and as holoprotein, either in complex with NAD(+) or NADP(+). Noticeably, the latter represents the first structure of an FDH enzyme in complex with NADP(+). This fine picture of the structural determinants involved in cofactor selectivity will possibly boost protein engineering of the new enzyme or other homolog FDHs in view of their biocatalytic exploitation for NADP(+) recycling.

Abstract
New peptidomimetic furin inhibitors with unnatural amino acid residues in the P3 position were synthesized. The most potent compound 4-guanidinomethyl-phenylacteyl-Arg-Tle-Arg-4-amidinobenzylamide (MI-1148) inhibits furin with a Ki value of 5.5 pM. The derivatives also strongly inhibit PC1/3, whereas PC2 is less affected. Selected inhibitors were tested in cell culture for antibacterial and antiviral activity against infectious agents known to be dependent on furin activity. A significant protective effect against anthrax and diphtheria toxin was observed in the presence of the furin inhibitors. Furthermore, the spread of the highly pathogenic H5N1 and H7N1 avian influenza viruses and propagation of canine distemper virus was strongly inhibited. Inhibitor MI-1148 was crystallized in complex with human furin. Its N-terminal guanidinomethyl group in the para position of the P5 phenyl ring occupies the same position as that found previously for a structurally related inhibitor containing this substitution in the meta position, thereby maintaining all of the important P5 interactions. Our results confirm that the inhibition of furin is a promising strategy for a short-term treatment of acute infectious diseases.
