CC -!- FUNCTION: Catalyzes the condensation of ATP and 5-phosphoribose 1-
CC diphosphate to form N'-(5'-phosphoribosyl)-ATP (PR-ATP). Has a crucial
CC role in the pathway because the rate of histidine biosynthesis seems to
CC be controlled primarily by regulation of HisG enzymatic activity.
CC {ECO:0000255|HAMAP-Rule:MF_00079}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1-(5-phospho-beta-D-ribosyl)-ATP + diphosphate = 5-phospho-
CC alpha-D-ribose 1-diphosphate + ATP; Xref=Rhea:RHEA:18473,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:58017,
CC ChEBI:CHEBI:73183; EC=2.4.2.17; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00079};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00079};
CC -!- ACTIVITY REGULATION: Feedback inhibited by histidine.
CC {ECO:0000255|HAMAP-Rule:MF_00079}.
CC -!- PATHWAY: Amino-acid biosynthesis; L-histidine biosynthesis; L-histidine
CC from 5-phospho-alpha-D-ribose 1-diphosphate: step 1/9.
CC {ECO:0000255|HAMAP-Rule:MF_00079}.
CC -!- SUBUNIT: Equilibrium between an active dimeric form, an inactive
CC hexameric form and higher aggregates. Interconversion between the
CC various forms is largely reversible and is influenced by the natural
CC substrates and inhibitors of the enzyme. {ECO:0000255|HAMAP-
CC Rule:MF_00079}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00079}.
CC -!- SIMILARITY: Belongs to the ATP phosphoribosyltransferase family. Long
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00079}.
