E biosynthesis Histidine biosynthesis genes in C. glutamicum Corynebacterium glutamicum strain

E biosynthesis Histidine biosynthesis genes in C. glutamicum Corynebacterium glutamicum strain AS019, a derivative of C. glutamicum ATCC 13059, was used for the initial genetic research on histidine biosynthesis. The genes hisA, encoding the 1-(5-phosphoribosyl)-5-[(5phosphoribosylamino)methylideneamino]imidazole-4 carboxamide (5ProFAR) isomerase, and hisF, encoding 1 subunit from the imidazole glycerol phosphate synthase, were identified by complementation of corresponding histidine auxotrophic E. coli mutants (Jung et al., 1998). The gene hisH, coding for the second subunit of imidazole glycerol phosphate synthase (Kim and Lee, 2001), and the genes hisG and hisE, coding for the ATP2013 The Authors.
