CC Evidence={ECO:0000256|ARBA:ARBA00001234, ECO:0000256|HAMAP-
CC Rule:MF_00098};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00098};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00098};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00098}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00098}.
CC -!- SIMILARITY: Belongs to the class-I aminoacyl-tRNA synthetase family.
CC MetG type 1 subfamily. {ECO:0000256|HAMAP-Rule:MF_00098}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
