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:0000256|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;
CC Evidence={ECO:0000256|ARBA:ARBA00000915, ECO:0000256|HAMAP-
CC Rule:MF_00079};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00079};
CC -!- ACTIVITY REGULATION: Feedback inhibited by histidine.
CC {ECO:0000256|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:0000256|ARBA:ARBA00004667, ECO:0000256|HAMAP-Rule:MF_00079}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00079}.
CC -!- SIMILARITY: Belongs to the ATP phosphoribosyltransferase family. Long
CC subfamily. {ECO:0000256|ARBA:ARBA00007955, ECO:0000256|HAMAP-
CC Rule:MF_00079}.
