Other name(s): GTNG_3158 (gene name)
Systematic name: FADH2:NAD(P)+ oxidoreductase
Comments: This enzyme, isolated from the bacterium Geobacillus thermodenitrificans, participates in the pathway of tryptophan degradation. The enzyme is part of a system that also includes a bifunctional riboflavin kinase/FMN adenylyltransferase and EC 220.127.116.11, anthranilate 3-monooxygenase (FAD). It can reduce either FAD or flavin mononucleotide (FMN) but prefers FAD. The enzyme has a slight preference for NADPH as acceptor. cf. EC 18.104.22.168, FAD reductase (NADH).
