General annotation (Comments)

Catalytic activity

5,10-methylenetetrahydrofolate + NADP+ = 5,10-methenyltetrahydrofolate + NADPH.

5,10-methenyltetrahydrofolate + H2O = 10-formyltetrahydrofolate.

ATP + formate + tetrahydrofolate = ADP + phosphate + 10-formyltetrahydrofolate.

Pathway

One-carbon metabolism; tetrahydrofolate interconversion.

Subunit structure

Homodimer By similarity.

Subcellular location

Cytoplasm By similarity.

Domain

This trifunctional enzyme consists of two major domains: an N-terminal part containing the methylene-THF dehydrogenase and cyclohydrolase activities and a larger C-terminal part containing formyl-THF synthetase activity.

Disruption phenotype

Knockout mice have revealed Mthfd1l as a monofunctional enzyme having only formyltetrahydrofolate synthetase activity and lacking methenyl-THF dehydrogenase and cyclohydrolase activities. Ref.5

Sequence similarities

In the N-terminal section; belongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.

In the C-terminal section; belongs to the formate--tetrahydrofolate ligase family.
