Enzyme Information
| 6.3.4.3 |
Formate--tetrahydrofolate ligase.
based on mapping to UniProt P11586
ATP + formate + tetrahydrofolate = ADP + phosphate + 10-formyltetrahydrofolate.
-!- In eukaryotes occurs as a trifunctional enzyme also having EC 1.5.1.5 and EC 3.5.4.9 activity.
|
| 3.5.4.9 |
Methenyltetrahydrofolate cyclohydrolase.
based on mapping to UniProt P11586
5,10-methenyltetrahydrofolate + H(2)O = 10-formyltetrahydrofolate.
|
| 1.5.1.5 |
Methylenetetrahydrofolate dehydrogenase (NADP(+)).
based on mapping to UniProt P11586
5,10-methylenetetrahydrofolate + NADP(+) = 5,10- methenyltetrahydrofolate + NADPH.
