Abstract
A novel amidase (TAM) was identified and cloned from the genome of Thauera sinica K11. The recombinant protein was purified to homogeneity by one-step affinity chromatography for up to 26.4-fold with a yield of 38.1%. Gel filtration chromatography and SDS-PAGE revealed that the enzyme was a tetramer with a subunit of approximately 37.5 kDa. The amidase exhibited the maximum acyl transfer activity at 45 °C and pH 7.0, and it was highly stable over a wide pH range of 6.0-11.0. Inhibition of enzyme activity was observed in the presence of metal ions, thiol reagents and organic solvents. TAM showed a broad substrate spectrum toward aliphatic, aromatic and heterocyclic amides. For linear aliphatic monoamides, the acyl transfer activity of TAM was decreased with the extension of the carbon chain length, and thus the highest activity of 228.2 U/mg was obtained when formamide was used as substrate. This distinct selectivity of amidase to linear aliphatic monoamides expanded the findings of signature amidases to substrate specificity.

[PMID: 32512219 DOI: 10.1016/j.biotechadv.2020.107574] [Citation(s) in RCA: 29] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Revised: 05/31/2020] [Accepted: 06/01/2020] [Indexed: 12/27/2022]
Abstract
Amidases (EC 3. 5. 1. X) are versatile biocatalysts for synthesis of chiral carboxylic acids, α-amino acids and amides due to their hydrolytic and acyl transfer activity towards the C-N linkages. They have been extensively exploited and studied during the past years for their high specific activity and excellent enantioselectivity involved in various biotechnological applications in pharmaceutical and agrochemical industries. Additionally, they have attracted considerable attentions in biodegradation and bioremediation owing to environmental pressures. Motivated by industrial demands, crystallographic investigations and catalytic mechanisms of amidases based on structural biology have witnessed a dramatic promotion in the last two decades. The protein structures showed that different types of amidases have their typical stuctural elements, such as the conserved AS domains in signature amidases and the typical architecture of metal-associated active sites in acetamidase/formamidase family amidases. This review provides an overview of recent research advances in various amidases, with a focus on their structural basis of phylogenetics, substrate specificities and catalytic mechanisms as well as their biotechnological applications. As more crystal structures of amidases are determined, the structure/function relationships of these enzymes will also be further elucidated, which will facilitate molecular engineering and design of amidases to meet industrial requirements.

Abstract
Abstract
A novel amidase gene (bami) was cloned from Brevibacterium epidermidis ZJB-07021 by combination of degenerate PCR and high-efficiency thermal asymmetric interlaced PCR (hiTAIL-PCR). The deduced amino acid sequence showed low identity (≤55 %) with other reported amidases. The bami gene was overexpressed in Escherichia coli, and the resultant inclusion bodies were refolded and purified to homogeneity with a recovery of 22.6 %. Bami exhibited a broad substrate spectrum towards aliphatic, aromatic and heterocyclic amides, and showed the highest acyl transfer activity towards butyramide with specific activity of 1331.0 ± 24.0 U mg−1. Kinetic analysis demonstrated that purified Bami exhibited high catalytic efficiency (414.9 mM−1 s−1) for acyl transfer of butyramide, with turnover number (K cat) of 3569.0 s−1. Key parameters including pH, substrate/co-substrate concentration, reaction temperature and catalyst loading were investigated and the Bami showed maximum acyl transfer activity at 50 °C, pH 7.5. Enzymatic catalysis of 200 mM butyramide with 15 μg mL−1 purified Bami was completed in 15 min with a BHA yield of 88.1 % under optimized conditions. The results demonstrated the great potential of Bami for the production of a variety of hydroxamic acids.
