CC   -!- FUNCTION: Catalyzes the transfer of a methyl group from 5-
CC       methyltetrahydrofolate to homocysteine resulting in methionine
CC       formation. {ECO:0000255|HAMAP-Rule:MF_00172}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-methyltetrahydropteroyltri-L-glutamate + L-homocysteine = L-
CC         methionine + tetrahydropteroyltri-L-glutamate; Xref=Rhea:RHEA:21196,
CC         ChEBI:CHEBI:57844, ChEBI:CHEBI:58140, ChEBI:CHEBI:58199,
CC         ChEBI:CHEBI:58207; EC=2.1.1.14; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00172};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00172};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00172};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC       pathway; L-methionine from L-homocysteine (MetE route): step 1/1.
CC       {ECO:0000255|HAMAP-Rule:MF_00172}.
CC   -!- SIMILARITY: Belongs to the vitamin-B12 independent methionine synthase
CC       family. {ECO:0000255|HAMAP-Rule:MF_00172}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAM84031.1; Type=Erroneous initiation; Evidence={ECO:0000305};
