>cd05212 NAD_bind_m-THF_DH_Cyclohyd_like NAD(P) binding domain of methylene-tetrahydrofolate dehydrogenase and methylene-tetrahydrofolate dehydrogenase/cyclohydrolase. NAD(P) binding domains of methylene-tetrahydrofolate dehydrogenase (m-THF DH) and m-THF DH/cyclohydrolase bifunctional enzymes (m-THF DH/cyclohydrolase). M-THF is a versatile carrier of activated one-carbon units. The major one-carbon folate donors are N-5 methyltetrahydrofolate, N5,N10-m-THF, and N10-formayltetrahydrofolate. The oxidation of metabolic intermediate m-THF to m-THF requires the enzyme m-THF DH. In addition, most DHs also have an associated cyclohydrolase activity which catalyzes its hydrolysis to N10-formyltetrahydrofolate. m-THF DH is typically found as part of a multifunctional protein in eukaryotes. NADP-dependent m-THF DH in mammals, birds and yeast are components of a trifunctional enzyme with DH, cyclohydrolase, and synthetase activities. Certain eukaryotic cells also contain homodimeric bifunctional
