FUNCTIONCatalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
CATALYTIC ACTIVITY Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + NADP(+) = (6R)- 5,10-methenyltetrahydrofolate + NADPH; Xref=Rhea:RHEA:22812, ChEBI:CHEBI:15636, ChEBI:CHEBI:57455, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=1.5.1.5;
CATALYTIC ACTIVITY Reaction=(6R)-5,10-methenyltetrahydrofolate + H2O = (6R)-10- formyltetrahydrofolate + H(+); Xref=Rhea:RHEA:23700, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57455, ChEBI:CHEBI:195366; EC=3.5.4.9;
PATHWAYOne-carbon metabolism; tetrahydrofolate interconversion.
SUBUNITHomodimer.
SIMILARITYBelongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.
