Abstract
Pyridoxal-5'-phosphate-(PLP-) dependent D-amino acid transaminases (DAATs) catalyze stereoselective reversible transfer of the amino group between D-amino acids and keto acids. In vivo DAATs are commonly known to synthesize D-glutamate for cell wall peptidoglycans. Today DAATs meet increasing attention for application in the synthesis of D-amino acids, whereas little is known about the mechanism of substrate recognition and catalytic steps of the D-amino acids conversion by DAATs. In this work, the pre-steady-state kinetics of the half-reactions of DAAT from Haliscomenobacter hydrossis with D-glutamate, D-alanine, D-leucine, and D-phenylalanine was examined at two wavelengths, 416 and 330 nm, using a stopped-flow technique. Monophasic kinetics was observed with specific substrates D-glutamate and D-alanine, whereas half-reactions with D-leucine and D-phenylalanine exhibited biphasic kinetics. All half-reactions proceeded until the complete conversion of PLP due to the release of the pyridoxamine-5'-phosphate form of cofactor from the holoenzyme . Comparison of kinetic parameters of half-reactions and the overall transamination reactions for D-leucine, D-phenylalanine revealed the increase in the rates of deamination of these substrates in the overall reaction with α-ketoglutarate. In the overall transamination reaction, the catalytic turnover rates for D-leucine and D-phenylalanine increased by 260 and 60 times, correspondingly, comparing with the slowest step rate constants in the half-reactions. We suggested the activating effect by a specific substrate α-ketoglutarate in the overall transamination reaction. The study of half-reactions helped to quantify the specificity of DAAT from H. hydrossis for D-amino acids with different properties. The results obtained are the first detailed analysis of half-reactions catalyzed by DAAT.

Abstract
D-amino acids are valuable building blocks for the synthesis of biologically active compounds and pharmaceuticals. The asymmetric synthesis of chiral amino acids from prochiral ketones using stereoselective enzymes is a well-known but far from exhausted approach for large-scale production. Herein, we investigated a pyridoxal-5′-phosphate-dependent D-amino acid transaminase from Haliscomenobacter hydrossis as a potential biocatalyst for the enzymatic asymmetric synthesis of optically pure aliphatic and aromatic D-amino acids. We studied the catalytic efficiency and stereoselectivity of transaminase from H. hydrossis in the amination of aliphatic and aromatic α-keto acids, using D-glutamate as a source of the amino group. We constructed a one-pot three-enzyme system, which included transaminase and two auxiliary enzymes, hydroxyglutarate dehydrogenase, and glucose dehydrogenase, to produce D-amino acids with a product yield of 95–99% and an enantiomeric excess of more than 99%. We estimated the stability of the transaminase and the cofactor leakage under reaction conditions. It was found that a high concentration of α-keto acids as well as a low reaction temperature (30 °C) can reduce the cofactor leakage under reaction conditions. The obtained results demonstrated the efficiency of transaminase from H. hydrossis in the asymmetric synthesis of enantiomerically pure D-amino acids.

Abstract
Developing (chemo)enzymatic cascades is very attractive for green synthesis, because they streamline multistep synthetic processes. In this Feature Article, we have summarized the recent advances in in vitro or whole-cell cascade reactions with a focus on the use of renewable bio-based resources as starting materials. This includes the synthesis of rare sugars (such as ketoses, L-ribulose, D-tagatose, myo-inositol or aminosugars) from readily available carbohydrate sources (cellulose, hemi-cellulose, starch), in vitro enzyme pathways to convert glucose to various biochemicals, cascades to convert 5-hydroxymethylfurfural and furfural obtained from lignin or xylose into novel precursors for polymer synthesis, the syntheses of phenolic compounds, cascade syntheses of aliphatic and highly reduced chemicals from plant oils and fatty acids, upgrading of glycerol or ethanol as well as cascades to transform natural L-amino acids into high-value (chiral) compounds. In several examples these processes have demonstrated their efficiency with respect to high space-time yields and low E-factors enabling mature green chemistry processes. Also, the strengths and limitations are discussed and an outlook is provided for improving the existing and developing new cascades.

The Uncommon Active Site of D-Amino Acid Transaminase from Haliscomenobacter hydrossis: Biochemical and Structural Insights into the New Enzyme. Molecules 2021; 26:molecules26165053.

Abstract
Among industrially important pyridoxal-5’-phosphate (PLP)-dependent transaminases of fold type IV D-amino acid transaminases are the least studied. However, the development of cascade enzymatic processes, including the synthesis of D-amino acids, renewed interest in their study. Here, we describe the identification, biochemical and structural characterization of a new D-amino acid transaminase from Haliscomenobacter hydrossis (Halhy). The new enzyme is strictly specific towards D-amino acids and their keto analogs; it demonstrates one of the highest rates of transamination between D-glutamate and pyruvate. We obtained the crystal structure of the Halhy in the holo form with the protonated Schiff base formed by the K143 and the PLP. Structural analysis revealed a novel set of the active site residues that differ from the key residues forming the active sites of the previously studied D-amino acids transaminases. The active site of Halhy includes three arginine residues, one of which is unique among studied transaminases. We identified critical residues for the Halhy catalytic activity and suggested functions of the arginine residues based on the comparative structural analysis, mutagenesis, and molecular modeling simulations. We suggested a strong positive charge in the O-pocket and the unshaped P-pocket as a structural code for the D-amino acid specificity among transaminases of PLP fold type IV. Characteristics of Halhy complement our knowledge of the structural basis of substrate specificity of D-amino acid transaminases and the sequence-structure-function relationships in these enzymes.

Abstract
Multistep enzyme-catalyzed cascade reactions are highly efficient in nature due to the confinement and concentration of the enzymes within nanocompartments. In this way, rates are exceptionally high, and loss of intermediates minimised. Similarly, extended enzyme cascades trapped and crowded within the nanoconfined environment of a porous conducting metal oxide electrode material form the basis of a powerful way to study and exploit myriad complex biocatalytic reactions and pathways. One of the confined enzymes, ferredoxin-NADP+ reductase, serves as a transducer, rapidly and reversibly recycling nicotinamide cofactors electrochemically for immediate delivery to the next enzyme along the chain, thereby making it possible to energize, control and observe extended cascade reactions driven in either direction depending on the electrode potential that is applied. Here we show as proof of concept the synthesis of aspartic acid from pyruvic acid or its reverse oxidative decarboxylation/deamination, involving five nanoconfined enzymes. Multistep enzymatic reactions (cascades) can be achieved by confining enzymes in synthetic materials, but ways to simultaneously energize, control and observe the reactions in real time are lacking. Here, bidirectional interconversion between aspartate and pyruvate by a five enzyme cascade trapped in electrode nanopores, addressable by laptop commands, is demonstrated.

Abstract
Abstract Cockroaches have existed for 300 million years and more than 4600 extant species have been described. Throughout their evolution, cockroaches have been associated with bacteria, and today Blattabacterium species flourish within specialized bacteriocytes, recycling nitrogen from host waste products. Cockroaches can disseminate potentially pathogenic bacteria via feces and other deposits, particularly members of the family Enterobacteriaceae, but also Staphylococcus and Mycobacterium species, and thus, they should be cleared from sites where hygiene is essential, such as hospitals and kitchens. On the other hand, cockroaches also carry bacteria that may produce metabolites or proteins with potential industrial applications. For example, an antibiotic-producing Streptomyces strain was isolated from the gut of the American cockroach Periplaneta americana. Other cockroach-associated bacteria, including but not limited to Bacillus, Enterococcus, and Pseudomonas species, can also produce bioactive metabolites that may be suitable for development as pharmaceuticals or plant protection products. Enzymes that degrade industrially relevant substrates, or that convert biomasses into useful chemical precursors, are also expressed in cockroach-derived bacteria and could be deployed for use in the food/feed, paper, oil, or cosmetics industries. The analysis of cockroach gut microbiomes has revealed a number of lesser-studied bacteria that may form the basis of novel taxonomic groups. Bacteria associated with cockroaches can therefore be dangerous or useful, and this review explores the bacterial clades that may provide opportunities for biotechnological exploitation. Key points • Members of the Enterobacteriaceae are the most frequently cultivated bacteria from cockroaches. • Cultivation-independent studies have revealed a diverse community, led by the phyla Bacteroidetes and Firmicutes. • Although cockroaches may carry pathogenic bacteria, most strains are innocuous and may be useful for biotechnological applications.

Abstract
The 22 genetically encoded amino acids (AAs) present in proteins (the 20 standard AAs together with selenocysteine and pyrrolysine), are commonly referred as proteinogenic AAs in the literature due to their appearance in ribosome-synthetized polypeptides. Beyond the borders of this key set of compounds, the rest of AAs are generally named imprecisely as non-proteinogenic AAs, even when they can also appear in polypeptide chains as a result of post-transductional machinery. Besides their importance as metabolites in life, many of D-α- and L-α-"non-canonical" amino acids (NcAAs) are of interest in the biotechnological and biomedical fields. They have found numerous applications in the discovery of new medicines and antibiotics, drug synthesis, cosmetic, and nutritional compounds, or in the improvement of protein and peptide pharmaceuticals. In addition to the numerous studies dealing with the asymmetric synthesis of NcAAs, many different enzymatic pathways have been reported in the literature allowing for the biosynthesis of NcAAs. Due to the huge heterogeneity of this group of molecules, this review is devoted to provide an overview on different established multienzymatic cascades for the production of non-canonical D-α- and L-α-AAs, supplying neophyte and experienced professionals in this field with different illustrative examples in the literature. Whereas the discovery of new or newly designed enzymes is of great interest, dusting off previous enzymatic methodologies by a "back and to the future" strategy might accelerate the implementation of new or improved multienzymatic cascades.

Abstract
In nature, the D-enantiomers of amino acids (D-AAs) are not used for protein synthesis and during evolution acquired specific and relevant physiological functions in different organisms. This is the reason for the surge in interest and investigations on these "unnatural" molecules observed in recent years. D-AAs are increasingly used as building blocks to produce pharmaceuticals and fine chemicals. In past years, a number of methods have been devised to produce D-AAs based on enantioselective enzymes. With the aim to increase the D-AA derivatives generated, to improve the intrinsic atomic economy and cost-effectiveness, and to generate processes at low environmental impact, recent studies focused on identification, engineering and application of enzymes in novel biocatalytic processes. The aim of this review is to report the advances in synthesis of D-AAs gathered in the past few years based on five main classes of enzymes. These enzymes have been combined and thus applied to multi-enzymatic processes representing in vitro pathways of alternative/exchangeable enzymes that allow the generation of an artificial metabolism for D-AAs synthetic purposes.

Abstract
Despite enormous progress in protein engineering, complemented by bioprocess engineering, the revolution awaiting the application of biocatalysis in the fine chemical industry has still not been fully realized. In order to achieve that, further research is required on several topics, including (1) rapid methods for protein engineering using machine learning, (2) mathematical modelling of multi-enzyme cascade processes, (3) process standardization, (4) continuous process technology, (5) methods to identify improvements required to achieve industrial implementation, (6) downstream processing, (7) enzyme stability modelling and prediction, as well as (8) new reactor technology. In this brief mini-review, the status of each of these topics will be briefly discussed.
