Enzyme Information

1.16.1.8
[Methionine synthase] reductase.
based on mapping to UniProt Q9UBK8
2 [methionine synthase]-methylcob(III)alamin + 2 S-adenosylhomocysteine + NADP(+) = 2 [methionine synthase]-cob(II)alamin + NADPH + 2 S-adenosyl-L- methionine.
-!- The substrate of the enzyme is the inactivated cobalt(II) form of EC 2.1.1.13. -!- Electrons are transferred from NADPH to FAD to FMN. -!- Formerly EC 2.1.1.135.
