RL Submitted (MAY-2012) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the transfer of a methyl group from 5-
CC methyltetrahydrofolate to homocysteine resulting in methionine
CC formation. {ECO:0000256|ARBA:ARBA00002777}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|PIRSR:PIRSR000382-2};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000256|PIRSR:PIRSR000382-
CC 2};
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:0000256|ARBA:ARBA00004681}.
CC -!- SIMILARITY: Belongs to the vitamin-B12 independent methionine synthase
CC family. {ECO:0000256|ARBA:ARBA00009553}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:CCI44194.1}.
