Protein attributes

Sequence length	284 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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-Rule MF_00079
Catalytic activity	1-(5-phospho-D-ribosyl)-ATP + diphosphate = ATP + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP-Rule MF_00079
Cofactor	Magnesium By similarity.
Enzyme regulation	Feedback inhibited by histidine By similarity. HAMAP-Rule MF_00079
Pathway	Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine from 5-phospho-alpha-D-ribose 1-diphosphate: step 1/9. HAMAP-Rule 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 By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the ATP phosphoribosyltransferase family. Long subfamily.
