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_01018}.
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         Rule:MF_01018};
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_01018}.
CC   -!- SUBUNIT: Heteromultimer composed of HisG and HisZ subunits.
CC       {ECO:0000255|HAMAP-Rule:MF_01018}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01018}.
CC   -!- DOMAIN: Lacks the C-terminal regulatory region which is replaced by
CC       HisZ.
CC   -!- SIMILARITY: Belongs to the ATP phosphoribosyltransferase family. Short
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_01018}.
