BRITE hierarchy
Sysname
aldehyde,FMNH2:oxygen oxidoreductase (1-hydroxylating, luminescing)
Reaction(IUBMB)
an aldehyde + FMNH2 + O2 = a carboxylate + FMN + H2O + hnu [RN:R03536]
Reaction(KEGG)
Substrate
aldehyde [CPD:C00071];
FMNH2 [CPD:C01847];
O2 [CPD:C00007]
Product
carboxylate [CPD:C00060];
FMN [CPD:C00061];
H2O [CPD:C00001];
hnu [CPD:C00205]
Comment
The reaction sequence involves incorporation of a molecule of oxygen into reduced FMN, and subsequent reaction with the aldehyde to form an activated FMN.H2O complex, which breaks down with emission of light. The enzyme is highly specific for reduced FMN, and for long-chain aliphatic aldehydes with eight carbons or more.
