Description
In enzymology, an alkanal monooxygenase (FMN-linked) (EC 1.14.14.3) is an enzyme that catalyzes the chemical reaction:RCHO + reduced FMN + O2↔ RCOOH + FMN + H2O + hnu. The 3 substrates of this enzyme are RCHO, reduced FMN, and O2, whereas its 4 products are RCOOH, FMN, H2O, and hn. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor.

Source
Vibrio fischeri (Photobacterium f)
Applications
Luciferase from Vibrio fischeri has been used in a study to assess kinetics of light emission and oxygen consumption by bioluminescent bacteria. It has also been used in a study to investigate the sensitivity of dark mutants of various strains of luminescent bacteria to reactive oxygen species.
Enzyme Commission Number

Specificity
Partially purified, soluble extracts containing FMN-dependent luciferase and NADH-and NADPH-dependent FMN reductases. Produces light in a system containing FMN, NADH or NADPH, and n-decyl aldehyde.
