Superfamily 3.40.50.360
Functional Family NAD(P)H-dependent FMN reductase

Enzyme Information

1.5.1.38
FMN reductase (NADPH).
based on mapping to UniProt P80644
FMNH(2) + NADP(+) = FMN + NADPH.
-!- The enzymes from bioluminescent bacteria contain FMN, while the enzyme from Escherichia coli does not. -!- The enzyme often forms a two-component system with monooxygenases such as luciferase. -!- Unlike EC 1.5.1.39, this enzyme does not use NADH as acceptor. -!- While FMN is the preferred substrate, the enzyme can also use FAD and riboflavin with lower activity. -!- Formerly EC 1.5.1.29 and EC 1.6.8.1.
