Abstract
(R)-selective transaminases show promise as catalysts for the asymmetric synthesis of chiral amines, which are building blocks of various small molecule drugs. However, their application is limited by poor substrate acceptance and low catalytic efficiency. Here, a potential (R)-selective transaminase from Fodinicurvata sediminis (FsTA) was identified through a substrate truncating strategy, and used as starting point for enzyme engineering toward catalysis of 4-hydroxy-2-butanone, a substrate that poses challenges in catalysis. Molecular docking and dynamics simulations revealed Y90 as the key residue responsible for poor substrate binding. Starting from the variant (Y90F, mut1) with initial activity, FsTA was systematically modified to improve substrate-binding through active site reshaping and consensus sequence strategy, yielding three variants (H30R, V152K, and Y156F) with improved activity. A quadruple mutation variant H30R/Y90F/V152K/Y156F (mut4) was also found to show a 7.95-fold greater catalytic efficiency (kcat/KM) than the initial variant mut1. Furthermore, mut4 also enhanced the thermostability of enzyme significantly, with the Tm value increasing by 10 °C. This variant also exhibited significantly improved activity toward a series of ketones that are either not accepted or poorly accepted by the wild-type. This study provides a basis for the rational design of an active to creating variants that can accommodate novel substrates.

A chromosome-level genome assembly of anesthetic drug-producing Anisodus acutangulus provides insights into its evolution and the biosynthesis of tropane alkaloids. PLANT COMMUNICATIONS 2024; 5:100680. [PMID: 37660252 PMCID: PMC10811374 DOI: 10.1016/j.xplc.2023.100680] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Revised: 08/16/2023] [Accepted: 08/30/2023] [Indexed: 09/04/2023]
Abstract
Tropane alkaloids (TAs), which are anticholinergic agents, are an essential class of natural compounds, and there is a growing demand for TAs with anesthetic, analgesic, and spasmolytic effects. Anisodus acutangulus (Solanaceae) is a TA-producing plant that was used as an anesthetic in ancient China. In this study, we assembled a high-quality, chromosome-scale genome of A. acutangulus with a contig N50 of 7.4 Mb. A recent whole-genome duplication occurred in A. acutangulus after its divergence from other Solanaceae species, which resulted in the duplication of ADC1 and UGT genes involved in TA biosynthesis. The catalytic activities of H6H enzymes were determined for three Solanaceae plants. On the basis of evolution and co-expressed genes, AaWRKY11 was selected for further analyses, which revealed that its encoded transcription factor promotes TA biosynthesis by activating AaH6H1 expression. These findings provide useful insights into genome evolution related to TA biosynthesis and have potential implications for genetic manipulation of TA-producing plants.

Abstract
ω-Transaminases (ω-TAs) show considerable potential for the synthesis of chiral amines. However, their low catalytic efficiency towards bulky substrates limits their application, and complicated catalytic mechanisms prevent precise enzyme design. Herein, we address this challenge using a mechanism-guided computational enzyme design strategy by reprograming the transition and ground states in key reaction steps. The common features among the three high-energy-barrier steps responsible for the low catalytic efficiency were revealed using quantum mechanics (QM). Five key residues were simultaneously tailored to stabilize the rate-limiting transition state with the aid of the Rosetta design. The 14 top-ranked variants showed 16.9-143-fold improved catalytic activity. The catalytic efficiency of the best variant, M9 (Q25F/M60W/W64F/I266A), was significantly increased, with a 1660-fold increase in kcat /Km and a 1.5-26.8-fold increase in turnover number (TON) towards various indanone derivatives.

Abstract
BACKGROUND The unnatural amino acid, L-2-aminobutyric acid (L-ABA) is an essential chiral building block for various pharmaceutical drugs, such as the antiepileptic drug levetiracetam and the antituberculosis drug ethambutol. The present study aims at obtaining variants of ω-transaminase from Ochrobactrum anthropi (OATA) with high catalytic activity to α-ketobutyric acid through protein engineering. RESULTS Based on the docking model using α-ketobutyric acid as the ligand, 6 amino acid residues, consisting of Y20, L57, W58, G229, A230 and M419, were chosen for saturation mutagenesis. The results indicated that L57C, M419I, and A230S substitutions demonstrated the highest elevation of enzymatic activity among 114 variants. Subsequently, double substitutions combining L57C and M419I caused a further increase of the catalytic efficiency to 3.2-fold. This variant was applied for threonine deaminase/OATA coupled reaction in a 50-mL reaction system with 300 mM L-threonine as the substrate. The reaction was finished in 12 h and the conversion efficiency of L-threonine into L-ABA was 94%. The purity of L-ABA is 75%, > 99% ee. The yield of L-ABA was 1.15 g. CONCLUSION This study provides a basis for further engineering of ω-transaminase for producing chiral amines from keto acids substrates.

Abstract
![]()
ω-Transaminases
(ω-TA) are attractive biocatalysts
for the production of chiral amines from prochiral ketones via asymmetric synthesis. However, the substrate scope of
ω-TAs is usually limited due to steric hindrance at the active
site pockets. We explored a protein engineering strategy using computational
design to expand the substrate scope of an (S)-selective
ω-TA from Pseudomonas jessenii (PjTA-R6) toward the production of bulky amines. PjTA-R6 is attractive for use in applied biocatalysis due
to its thermostability, tolerance to organic solvents, and acceptance
of high concentrations of isopropylamine as amino donor. PjTA-R6 showed no detectable activity for the synthesis of six bicyclic
or bulky amines targeted in this study. Six small libraries composed
of 7–18 variants each were separately designed via computational methods and tested in the laboratory for ketone to
amine conversion. In each library, the vast majority of the variants
displayed the desired activity, and of the 40 different designs, 38
produced the target amine in good yield with >99% enantiomeric
excess.
This shows that the substrate scope and enantioselectivity of PjTA mutants could be predicted in silico with high accuracy. The single mutant W58G showed the best performance
in the synthesis of five structurally similar bulky amines containing
the indan and tetralin moieties. The best variant for the other bulky
amine, 1-phenylbutylamine, was the triple mutant W58M + F86L + R417L,
indicating that Trp58 is a key residue in the large binding pocket
for PjTA-R6 redesign. Crystal structures of the two
best variants confirmed the computationally predicted structures.
The results show that computational design can be an efficient approach
to rapidly expand the substrate scope of ω-TAs to produce enantiopure
bulky amines.

Creation of a robust and R-selective ω-amine transaminase for the asymmetric synthesis of sitagliptin intermediate on a kilogram scale. Enzyme Microb Technol 2020; 141:109655.

Abstract
The creation of an R-selective ω-amine transaminase (ω-ATA) as biocatalyst is crucial for the asymmetric amination of prochiral ketones to produce sitagliptin intermediates because rare ω-ATAs are R-selective in nature and most of them suffer from poor stability and low activity toward bulky prochiral ketones. Here, the gene of an R-selective ω-ATA was cloned from Arthrobacter cumminsii ZJUT212 (AcATA) and expressed in Escherichia coli. The best variants (M1 + M122H and M1+T134 G) were obtained using a semi-rational protein design after screening. These variants not only exhibited improved activity and substrate affinity but also enhanced stability in aqueous phase containing 20 % dimethyl sulfoxide. The conversion of asymmetric amination on 50 g/L pro-sitagliptin ketone PTfpB (1-[1-piperidinyl]-4-[2,4,5-trifluorophenyl]-1,3-butanedione) achieved 92 %, with an extremely high e.e. of >99 %, using 2 gDCW/L E. coli cells harboring M1 + M122H as biocatalyst. In the kilogram-scale experiment, approximately 40 kg of (R)-APTfpB (e.e. >99 %) was produced within 30 h when 50 kg PTfpB was used as the substrate. Furthermore, the space-time yield reached ≈32 g/(L·d).

Strategic single point mutation yields a solvent- and salt-stable transaminase from Virgibacillus sp. in soluble form. Sci Rep 2018; 8:16441.

Abstract
A new transaminase (VbTA) was identified from the genome of the halotolerant marine bacterium Virgibacillus 21D. Following heterologous expression in Escherichia coli, it was located entirely in the insoluble fraction. After a single mutation, identified via sequence homology analyses, the VbTA T16F mutant was successfully expressed in soluble form and characterised. VbTA T16F showed high stability towards polar organic solvents and salt exposure, accepting mainly hydrophobic aromatic amine and carbonyl substrates. The 2.0 Å resolution crystal structure of VbTA T16F is here reported, and together with computational calculations, revealed that this mutation is crucial for correct dimerisation and thus correct folding, leading to soluble protein expression.

Abstract
Amine transaminases are important biocatalysts for the synthesis of chiral primary amines. Unlike many enzymes that have been employed for the synthesis of optically active amines, amine transaminases are capable of asymmetric synthesis and do not rely on costly cofactors that must be regenerated in situ. However, their application as general catalysts for the preparation of amines is hampered by a limited substrate scope, substrate and (co)product inhibition and difficulties associated with displacing challenging reaction equilibrium. There has been important progress made to overcome these challenges, including the development of enzymes with broader substrate scope and the design of methodology to effectively displace the reaction equilibrium. Amine transaminases are also being applied in an increasing range of (chemo)enzymatic cascades and immobilized for applications in flow.

Abstract
Transaminases, which catalyze the stereoselective transfer of an amino group between an amino donor and a prochiral ketone substrate, are interesting biocatalytic tools for the generation of optically pure chiral amines. In particular, amine transaminases (ATAs) are of industrial interest because they are capable of performing reductive amination reactions using a broad range of amine donors and acceptors. The most remarkable example of ATAs industrial application is in the production process of the anti-hyperglycaemic drug sitagliptin (Januvia®/Janumet®), which generated around 6 billion U.S. dollars of revenue to Merck in 2016. In this review, an update about the availability of microbial ATAs, discovered by both screening and database-mining approaches, or obtained by protein engineering of wild-type enzymes, will be provided. Current challenges in ATAs application and possible solutions will be also discussed. In particular, innovative biocatalytic process strategies aimed at the improvement of ATAs performances in chiral amines synthesis, e.g., using in situ product removal process strategies or flow reactors, will be presented. The progress in the industrial exploitation of these enzymes will be highlighted by selected examples of large-scale ATA-catalyzed processes.

Abstract
Hot spring metagenomes, prepared from samples collected at temperatures ranging from 55 to 95 °C, were submitted to an in silico screening aimed at the identification of novel amine transaminases (ATAs), valuable biocatalysts for the preparation of optically pure amines. Three novel (S)-selective ATAs, namely Is3-TA, It6-TA, and B3-TA, were discovered in the metagenome of samples collected from hot springs in Iceland and in Italy, cloned from the corresponding metagenomic DNAs and overexpressed in recombinant form in E. coli. Functional characterization of the novel ATAs demonstrated that they all possess a thermophilic character and are capable of performing amine transfer reactions using a broad range of donor and acceptor substrates, thus suggesting a good potential for practical synthetic applications. In particular, the enzyme B3-TA revealed to be exceptionally thermostable, retaining 85% of activity after 5 days of incubation at 80 °C and more than 40% after 2 weeks under the same condition. These results, which were in agreement with the estimation of an apparent melting temperature around 88 °C, make B3-TA, to the best of our knowledge, the most thermostable natural ATA described to date. This biocatalyst showed also a good tolerance toward different water-miscible and water-immiscible organic solvents. A detailed inspection of the homology-based structural model of B3-TA showed that the overall active site architecture of mesophilic (S)-selective ATAs was mainly conserved in this hyperthermophilic homolog. Additionally, a subfamily of B3-TA-like transaminases, mostly uncharacterized and all from thermophilic microorganisms, was identified and analyzed in terms of phylogenetic relationships and sequence conservation.
