CC   -!- FUNCTION: Required for the first step of histidine biosynthesis. May
CC       allow the feedback regulation of ATP phosphoribosyltransferase activity
CC       by histidine. {ECO:0000255|HAMAP-Rule:MF_00125}.
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_00125}.
CC   -!- SUBUNIT: Heteromultimer composed of HisG and HisZ subunits.
CC       {ECO:0000255|HAMAP-Rule:MF_00125}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00125}.
CC   -!- MISCELLANEOUS: This function is generally fulfilled by the C-terminal
CC       part of HisG, which is missing in some bacteria such as this one.
CC   -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC       HisZ subfamily. {ECO:0000255|HAMAP-Rule:MF_00125}.
