General annotation (Comments)

Function	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 By similarity. HAMAP MF_00079
Catalytic activity	1-(5-phospho-D-ribosyl)-ATP + diphosphate = ATP + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP MF_00079
Cofactor	Magnesium. HAMAP MF_00079
Enzyme regulation	Feedback inhibited by histidine. Also inhibited by AMP. HAMAP MF_00079
Pathway	Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 1/9. HAMAP MF_00079
Subunit structure	Equilibrium between an active dimeric form, an inactive hexameric form and higher aggregates. Interconversion between the various forms is largely reversible and is influenced by the natural substrates and inhibitors of the enzyme. HAMAP MF_00079
Subcellular location	Cytoplasm By similarity HAMAP MF_00079.
Sequence similarities	Belongs to the ATP phosphoribosyltransferase family. Long subfamily.
