ID 1.5.1.38 DE FMN reductase (NADPH). AN flavin reductase P. CA FMNH2 + NADP(+) = FMN + 2 H(+) + NADPH. CC -!- The enzymes from bioluminescent bacteria contain FMN, while the CC enzyme from Escherichia coli does not. CC -!- The enzyme often forms a two-component system with monooxygenases CC such as luciferase. CC -!- Unlike EC 1.5.1.39, this enzyme does not use NADH as acceptor. CC -!- While FMN is the preferred substrate, the enzyme can also use FAD and CC riboflavin with lower activity. CC -!- Formerly EC 1.5.1.29 and EC 1.6.8.1.
