>TIGR00007 TIGR00007 phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase; InterPro: IPR006063 1-(5-phosphoribosyl)-5-[(5-phosphoribosylamino)methylideneamino] imidazole-4-carboxamide isomerase (5.3.1.16 from EC), also known as Phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase or HisA, catalyses the fourth step in histidine biosynthesis. HisA from Lactococcus lactis was found to be inactive . The putative HisA from Thermotoga maritima, is a conspicuous outlier to the set of all other HisA, including experimental HisA from the bacterium E. coli and the Archaeaon Methanococcus voltae. Neighbor joining shows HisA from Thermotoga maritima to be within the HisA family (with HisF as an outgroup) but with a long branch. ; GO: 0003949 1-(5-phosphoribosyl)-5-[(5-phosphoribosylamino)methylideneamino]imidazole-4-carboxamide isomerase activity, 0000105 histidine biosynthetic process.
