ENZYME entry: EC 1.5.1.38

Accepted Name
FMN reductase (NADPH).
Alternative Name(s)
flavin reductase P.
Reaction catalysed
FMNH2 + NADP(+) <=> FMN + 2 H(+) + NADPH
Comment(s)
  • 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.
