C-1-tetrahydrofolate synthase, cytoplasmic also known as C1-THF synthase is an enzyme that in humans is encoded by the MTHFD1 (methylenetetrahydrofolate dehydrogenase 1) gene.^[3][4][5]

Function

This gene encodes a protein that possesses three distinct enzymatic activities, methylenetetrahydrofolate dehydrogenase (1.5.1.5), methenyltetrahydrofolate cyclohydrolase (3.5.4.9) and formate–tetrahydrofolate ligase (6.3.4.3). Each of these activities catalyzes one of three sequential reactions in the interconversion of 1-carbon derivatives of tetrahydrofolate, which are substrates for methionine, thymidylate, and de novo purine syntheses. The trifunctional enzymatic activities are conferred by two major domains, an aminoterminal portion containing the dehydrogenase and cyclohydrolase activities and a larger synthetase domain.^[5][6]
