== Function ==
[https://www.uniprot.org/uniprot/HIS1_ECOLI HIS1_ECOLI] 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.[HAMAP-Rule:MF_00079]
