الوصف: | Two genes encoding nitrilases with different properties have been found in an Alcaligenes denitrificans C-32 strain with high nitrilase activity that is currently used as a biocatalyst for commercial ammonium acrylate production. Both genes were expressed in E. coli, and the properties of the recombinant nitrilases were studied. One of these genes, which is designated as nitC1, controlled the formation of nitrilase that preferred aliphatic nitriles (acrylonitrile and butyronitrile) as best substrates. The nucleotide sequence of the gene nitC1 was almost (99%) identical to the gene sequence of an aliphatic nitrilase from Acidovorax facilis 72W (DQ4444267). In turn, nitC2 had a high level of homology (85%) with the arylacetonitrilase gene from Alcaligenes faecalis JM3 (D13419). Benzyl cyanide was shown to be the best substrate for nitC2-encoded nitrilase. In light of the results of DNA homology and differences in substrate specificity, the NitC2 and NitC1 nitrilases from Alcaligenes denitrificans C-32 were allocated to the groups of aliphatic nitrilases and arylacetonitrilases, respectively. |
