IUBMB 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].

The expected taxonomic range for this enzyme is: Bacteria, Archaea, Eukaryota
