CC   -!- FUNCTION: Catalyzes the oxidation of 5,10-
CC       methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and
CC       then the hydrolysis of 5,10-methenyltetrahydrofolate to 10-
CC       formyltetrahydrofolate. {ECO:0000256|HAMAP-Rule:MF_01576,
CC       ECO:0000256|SAAS:SAAS01082560}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + NADP(+) =
CC         5,10-methenyltetrahydrofolate + NADPH; Xref=Rhea:RHEA:22812,

CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5,10-methenyltetrahydrofolate + H2O = (6S)-10-
CC         formyltetrahydrofolate + H(+); Xref=Rhea:RHEA:23700,

CC         Rule:MF_01576, ECO:0000256|SAAS:SAAS01118660};
CC   -!- PATHWAY: One-carbon metabolism; tetrahydrofolate interconversion.
CC       {ECO:0000256|HAMAP-Rule:MF_01576, ECO:0000256|SAAS:SAAS01082548}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01576,
CC       ECO:0000256|SAAS:SAAS01082565}.
CC   -!- SIMILARITY: Belongs to the tetrahydrofolate
CC       dehydrogenase/cyclohydrolase family. {ECO:0000256|HAMAP-
CC       Rule:MF_01576, ECO:0000256|SAAS:SAAS01082557}.
CC   -!- CAUTION: Lacks conserved residue(s) required for the propagation
CC       of feature annotation. {ECO:0000256|HAMAP-Rule:MF_01576}.
