BRITE hierarchy
Sysname
3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione,FMNH2:oxygen oxidoreductase
Reaction(IUBMB)
3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione + FMNH2 + O2 = 3,4-dihydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione + FMN + H2O [RN:R09819]
Reaction(KEGG)
Substrate
3-hydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione [CPD:C19944];
FMNH2 [CPD:C01847];
O2 [CPD:C00007]
Product
3,4-dihydroxy-9,10-secoandrosta-1,3,5(10)-triene-9,17-dione [CPD:C04793];
FMN [CPD:C00061];
H2O [CPD:C00001]
Comment
This bacterial enzyme participates in the degradation of several steroids, including cholesterol and testosterone. It can use either FADH or FMNH2 as flavin cofactor. The enzyme forms a two-component system with a reductase (HsaB) that utilizes NADH to reduce the flavin, which is then transferred to the oxygenase subunit.
