| Accepted name: |
bacterial luciferase |
| 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 1.13.12.18, dinoflagellate luciferase. |
