Enzyme Information

Bacterial luciferase.
based on mapping to UniProt P07739
A long-chain aldehyde + FMNH(2) + O(2) = a long-chain fatty acid + FMN + H(2)O + light.
-!- 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.
