== Function == | |||
[[http://www.uniprot.org/uniprot/HISZ_PSYA2 HISZ_PSYA2]] Required for the first step of histidine biosynthesis. May allow the feedback regulation of ATP phosphoribosyltransferase activity by histidine.[HAMAP-Rule:MF_00125] [[http://www.uniprot.org/uniprot/HIS1_PSYA2 HIS1_PSYA2]] Catalyzes the condensation of ATP and 5-phosphoribose 1-diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial role in the pathway because the rate of histidine biosynthesis seems to be controlled primarily by regulation of HisG enzymatic activity. | |||
