CC -!- FUNCTION: Required for the first step of histidine biosynthesis. May
CC allow the feedback regulation of ATP phosphoribosyltransferase activity
CC by histidine. {ECO:0000256|ARBA:ARBA00025246, ECO:0000256|HAMAP-
CC 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:0000256|ARBA:ARBA00004667, ECO:0000256|HAMAP-Rule:MF_00125}.
CC -!- SUBUNIT: Heteromultimer composed of HisG and HisZ subunits.
CC {ECO:0000256|HAMAP-Rule:MF_00125}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|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 {ECO:0000256|HAMAP-Rule:MF_00125}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC HisZ subfamily. {ECO:0000256|ARBA:ARBA00005539, ECO:0000256|HAMAP-
CC Rule:MF_00125}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:OUV21108.1}.
