" /> methylenetetrahydrofolate dehydrogenase (NADP) - CISMeF





Preferred Label : methylenetetrahydrofolate dehydrogenase (NADP);

MeSH definition : An NADP-dependent oxidoreductase that catalyses the conversion of 5,10-methyleneterahydrofolate to 5,10-methenyl-tetrahydrofolate. In higher eukaryotes a trifunctional enzyme exists with additional METHENYLTETRAHYDROFOLATE CYCLOHYDROLASE and FORMATE-TETRAHYDROFOLATE LIGASE activity. The enzyme plays an important role in the synthesis of 5-methyltetrahydrofolate, the methyl donor for the VITAMIN B12-dependent remethylation of HOMOCYSTEINE to METHIONINE via METHIONINE SYNTHETASE.;

MeSH synonym : methylenetetrahydrofolate dehydrogenase; dehydrogenase, methylenetetrahydrofolate; methylenetetrahydrofolate dehydrogenase (NADP );

MeSH CAS label : 5,10-Methylenetetrahydrofolate:NADP oxidoreductase;

Registry Number MeSH : EC 1.5.1.5;

MeSH annotation : do not confuse with METHYLENETETRAHYDROFOLATE DEHYDROGENASE (NAD );

Is substance : O;

UNII : EC 1.5.1.5;
