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.

Not as easy as pi : An insertional residue does not explain the pi-helix gain-of-function in two-component FMN reductases.
