Enzymatic and genetic characterization of firefly luciferase and Drosophila CG6178 as a fatty acyl-CoA synthetase.

Recently we found that firefly luciferase is a bifunctional enzyme, catalyzing not only the luminescence reaction but also long-chain fatty acyl-CoA synthesis. Further, the gene product of CG6178 (CG6178), an ortholog of firefly luciferase in Drosophila melanogaster, was found to be a long-chain fatty acyl-CoA synthetase and dose not function as a luciferase. We investigated the substrate specificities of firefly luciferase and CG6178 as an acyl-CoA synthetase utilizing a series of carboxylic acids. The results indicate that these enzymes synthesize acyl-CoA efficiently from various saturated medium-chain fatty acids. Lauric acid is the most suitable substrate for these enzymes, and the product of lauroyl CoA was identified with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). Phylogenetic analysis indicated that firefly luciferase and CG6178 genes belong to the group of plant 4-coumarate:CoA ligases, and not to the group of medium- and long-chain fatty acyl-CoA synthetases in mammals. These results suggest that insects have a novel type of fatty acyl-CoA synthetase.[1]
