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 SAAS SAAS013820

Cofactor

Magnesium By similarity. HAMAP MF_00079

Enzyme regulation

Feedback inhibited by histidine By similarity. 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 SAAS SAAS013820

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. HAMAP MF_00079

Subcellular location

Cytoplasm By similarity HAMAP MF_00079.

Sequence similarities

Belongs to the ATP phosphoribosyltransferase family. Long subfamily. HAMAP MF_00079
