Protein attributes

Sequence length	654 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Catalyzes the conversion of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate, a co-substrate for homocysteine remethylation to methionine.
Catalytic activity	5-methyltetrahydrofolate + NAD(P)+ = 5,10-methylenetetrahydrofolate + NAD(P)H.
Cofactor	FAD By similarity.
Enzyme regulation	Allosterically regulated by S-adenosylmethionine By similarity.
Pathway	One-carbon metabolism; tetrahydrofolate interconversion.
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the methylenetetrahydrofolate reductase family.
