从链霉菌属中克隆了一种新的腈水解酶超家族酰胺酶基因,命名为 azl13。 211726.生物信息和生化分析表明Azl13属于腈水解酶超家族第13分支中的一个新亚家族。 His6-Azl13 在大肠杆菌 BL21(DE3) 中表达,预期分子量为 31 kDa,酶活性在 40 ℃、pH 8.0 时最佳。 His6-Azl13 具有酰胺酶、芳基酰胺酶和酰基转移酶活性,并且显示出异常宽的底物谱。 His6-Azl13 对 4-胍基丁酰胺(可能是其天然底物)活性最强,对短链脂肪族酰胺活性中等,对水解芳香族和杂环酰胺活性弱。 His6-Azl13 还催化从乙酰胺或除草剂敌稗到羟胺的酰基转移。底物光谱与假单胞菌酰胺酶 RamA 的底物光谱不同,可能反映了高盐度适应。 Azl13 的广泛底物谱可能用于化学合成和生物降解。
A novel nitrilase superfamily amidase gene, designated azl13, was cloned from Streptomyces sp. 211726. Bioinformatic and biochemical analysis indicated that Azl13 belongs to a new subfamily in branch 13 of the nitrilase superfamily. His6-Azl13 was expressed in Escherichia coli BL21(DE3) and had the expected molecular mass of 31 kDa, and the enzymatic activity was best at 40 °C, pH 8.0. His6-Azl13 had amidase, aryl acylamidase, and acyl transferase activities, and it displayed an unusually wide substrate spectrum. His6-Azl13 was most active on 4-guanidinobutyramide, which is probably its natural substrate, moderately active on short-chain aliphatic amides and weakly active hydrolyzing aromatic and heterocyclic amides. His6-Azl13 also catalyzed acyl transfer to hydroxylamine from acetamide or the herbicide propanil. The substrate spectrum differs from that of the Pseudomonas amidase RamA, probably reflecting high salinity adaptation. The broad substrate spectrum of Azl13 is potentially useful for chemical synthesis and biodegradation.
