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.
