Reaction: a long-chain aldehyde + FMNH2 + O2 = a long-chain fatty acid + FMN + H2O + hν
Other name(s): aldehyde monooxygenase; luciferase; Vibrio fischeri luciferase; alkanal,reduced-FMN:oxygen oxidoreductase (1-hydroxylating, luminescing); alkanal,FMNH2:oxygen oxidoreductase (1-hydroxylating, luminescing); alkanal monooxygenase (FMN); aldehyde,FMNH2:oxygen oxidoreductase (1-hydroxylating, luminescing)
Systematic name: long-chain-aldehyde,FMNH2:oxygen oxidoreductase (1-hydroxylating, luminescing)
Comments: The reaction sequence starts with the incorporation of a molecule of oxygen into reduced FMN bound to the enzyme, forming luciferase peroxyflavin. The peroxyflavin interacts with an aliphatic long-chain aldehyde, producing a highly fluorescent species believed to be luciferase hydroxyflavin. The enzyme is highly specific for reduced FMN and for long-chain aliphatic aldehydes with eight carbons or more. The highest efficiency is achieved with tetradecanal. cf. EC 184.108.40.206, dinoflagellate luciferase.
