CC -!- FUNCTION: Is required not only for elongation of protein synthesis but
CC also for the initiation of all mRNA translation through initiator
CC tRNA(fMet) aminoacylation. {ECO:0000256|ARBA:ARBA00003314,
CC ECO:0000256|HAMAP-Rule:MF_01228}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-methionine + tRNA(Met) = AMP + diphosphate + L-
CC methionyl-tRNA(Met); Xref=Rhea:RHEA:13481, Rhea:RHEA-COMP:9667,

CC Rule:MF_01228};
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_01228}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01228}.
CC -!- SIMILARITY: Belongs to the class-I aminoacyl-tRNA synthetase family.
CC {ECO:0000256|RuleBase:RU363039}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01228}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
