General annotation (Comments)

Function

Catalyzes the transfer of a methyl group from 5-methyltetrahydrofolate to homocysteine resulting in methionine formation By similarity. HAMAP-Rule MF_00172 SAAS SAAS006276

Catalytic activity

5-methyltetrahydropteroyltri-L-glutamate + L-homocysteine = tetrahydropteroyltri-L-glutamate + L-methionine. HAMAP-Rule MF_00172 SAAS SAAS006276

Cofactor

Binds 1 zinc ion per subunit By similarity. HAMAP-Rule MF_00172

Pathway

Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-methionine from L-homocysteine (MetE route): step 1/1. HAMAP-Rule MF_00172 SAAS SAAS006276

Sequence similarities

Belongs to the vitamin-B12 independent methionine synthase family. HAMAP-Rule MF_00172
