CC   -!- FUNCTION: Attaches a formyl group to the free amino group of methionyl-
CC       tRNA(fMet). The formyl group appears to play a dual role in the
CC       initiator identity of N-formylmethionyl-tRNA by promoting its
CC       recognition by IF2 and preventing the misappropriation of this tRNA by
CC       the elongation apparatus. {ECO:0000250|UniProtKB:P23882}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(6S)-10-formyltetrahydrofolate + L-methionyl-tRNA(fMet) =
CC         (6S)-5,6,7,8-tetrahydrofolate + H(+) + N-formyl-L-methionyl-
CC         tRNA(fMet); Xref=Rhea:RHEA:24380, Rhea:RHEA-COMP:9952, Rhea:RHEA-
CC         COMP:9953, ChEBI:CHEBI:15378, ChEBI:CHEBI:57453, ChEBI:CHEBI:57454,
CC         ChEBI:CHEBI:78530, ChEBI:CHEBI:78844; EC=2.1.2.9;
CC         Evidence={ECO:0000250|UniProtKB:P23882};
CC   -!- SIMILARITY: Belongs to the Fmt family. {ECO:0000305}.
