1A4I - PubMed Abstract: 
The interconversion of two major folate one-carbon donors occurs through the sequential activities of NAD(P)-dependent methylene[H4]folate dehydrogenase (D) and methenyl[H4]folate cyclohydrolase (C). These activities often coexist as part of a multifunctional enzyme and there are several lines of evidence suggesting that their substrates bind at overlapping sites. Little is known, however, about the nature of this site or the identity of the active-site residues for this enzyme family.
