>TIGR01141 hisC histidinol-phosphate aminotransferase; InterPro: IPR005861 The biosynthesis of histidine is a central metabolic process in organisms ranging from bacteria to yeast and plants. The seventh step in the synthesis of histidine within eubacteria is carried out by a pyridoxal-5'-phosphate (PLP)-dependent l-histidinol phosphate aminotransferase (HisC, 2.6.1.9 from EC). HisC is a dimeric enzyme with a mass of approximately 80 kDa. Like most PLP-dependent enzymes, each HisC monomer consists of two domains, a larger PLP-binding domain having an alpha/beta/alpha topology, and a smaller domain. An N-terminal arm contributes to the dimerization of the two monomers . ; GO: 0004400 histidinol-phosphate transaminase activity, 0000105 histidine biosynthetic process.
