General annotation (Comments)

Function

Involved in the regulation of homocysteine metabolism. Converts homocysteine to methionine using S-methylmethionine (SMM) as a methyl donor. Ref.6

Catalytic activity

S-methyl-L-methionine + L-homocysteine = 2 L-methionine. Ref.6

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 (BhmT route): step 1/1.

Subunit structure

Homotetramer By similarity.

Tissue specificity

Expressed in fetal heart, lung, liver, kidney and eye. Ref.1

Sequence similarities

Contains 1 Hcy-binding domain.
