General annotation (Comments)

Function	Catalyzes the transfer of a methyl group from 5-methyltetrahydrofolate to homocysteine resulting in methionine formation By similarity.
Catalytic activity	5-methyltetrahydropteroyltri-L-glutamate + L-homocysteine = tetrahydropteroyltri-L-glutamate + L-methionine. HAMAP MF_00172
Cofactor	Binds 1 zinc ion per subunit By similarity.
Pathway	Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-methionine from L-homocysteine (MetE route): step 1/1. HAMAP MF_00172
Sequence similarities	Belongs to the vitamin-B12 independent methionine synthase family.
