Bifunctional protein FolD

Gene

folD

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10-methenyltetrahydrofolate to 10-formyltetrahydrofolate. This enzyme is specific for NADP.UniRule annotation1 Publication

Catalytic activityi

5,10-methylenetetrahydrofolate + NADP+ = 5,10-methenyltetrahydrofolate + NADPH.UniRule annotation
5,10-methenyltetrahydrofolate + H2O = 10-formyltetrahydrofolate.UniRule annotation

Pathwayi: tetrahydrofolate interconversion
