IUBMB Comments

In humans, the enzyme is a flavoprotein containing FAD and FMN. The substrate of the enzyme is the inactivated cobalt(II) form of EC 2.1.1.13, methionine synthase. Electrons are transferred from NADPH to FAD to FMN. Defects in this enzyme lead to hereditary hyperhomocysteinemia.

The expected taxonomic range for this enzyme is: Eukaryota, Bacteria

Synonyms
methionine synthase reductase, nadph-dependent diflavin oxidoreductase, more
