Function
function
Catalyzes the transfer of a methyl group from 5-methyltetrahydrofolate to homocysteine resulting in methionine formation.
Catalytic activity
- 5-methyltetrahydropteroyltri-L-glutamate + L-homocysteine = tetrahydropteroyltri-L-glutamate + L-methionine
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 zinc ion per subunit.
Note: Binds 2 Zn2+ ions per subunit.
Pathway
Amino-acid biosynthesis; L-methionine biosynthesis via de novo pathway; L-methionine from L-homocysteine (MetE route): step 1/1.
