PFAM accession number:PF02882
Interpro abstract (IPR020631):

Enzymes that participate in the transfer of one-carbon units require the coenzyme tetrahydrofolate (THF). Various reactions generate one-carbon derivatives of THF, which can be interconverted between different oxidation states by methylene-THF dehydrogenase ( EC ), methenyl-THF cyclohydrolase ( EC ) and formyl-THF synthetase ( EC ) [ (PUBMED:2541774) (PUBMED:8485162) ]. The dehydrogenase and cyclohydrolase activities are expressed by a variety of multifunctional enzymes, including the tri-functional eukaryotic C1-tetrahydrofolate synthase [ (PUBMED:2541774) ]; a bifunctional eukaryotic mitochondrial protein; and the bifunctional Escherichia coli folD protein [ (PUBMED:2541774) (PUBMED:8485162) ]. Methylene-tetrahydrofolate dehydrogenase and methenyltetrahydrofolate cyclo-hydrolase share an overlapping active site [ (PUBMED:2541774) ], and as such are usually located together in proteins, acting in tandem on the carbon-nitrogen bonds of substrates other than peptide bonds.

This entry represents the NAD(P)-binding domain found in these enzymes.

GO function:methylenetetrahydrofolate dehydrogenase (NADP+) activity (GO:0004488)
