CC -!- FUNCTION: Catalyzes the transfer of a methyl group to L-homocysteine
CC resulting in methionine formation. The physiological methyl donor is
CC unknown. {ECO:0000255|HAMAP-Rule:MF_00288}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00288};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00288};
CC -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via de novo
CC pathway. {ECO:0000255|HAMAP-Rule:MF_00288}.
CC -!- SIMILARITY: Belongs to the archaeal MetE family. {ECO:0000255|HAMAP-
CC Rule:MF_00288, ECO:0000305}.
