Accepted name: |

Other name(s): |
NADH-FMN reductase; NADH-dependent FMN reductase; NADH:FMN oxidoreductase; NADH:flavin oxidoreductase |
Systematic name: |
FMNH2:NAD+ oxidoreductase |
Comments: |
The enzyme often forms a two-component system with monooxygenases. Unlike EC 1.5.1.38, FMN reductase (NADPH), and EC 1.5.1.39, FMN reductase [NAD(P)H], this enzyme has a strong preference for NADH over NADPH, although some activity with the latter is observed [1,2].
While FMN is the preferred substrate, FAD can also be used with much lower activity [1,3]. |
