LuxC

LuxC
PFAM accession number:PF05893
Interpro abstract (IPR008670): This family consists of several bacterial Acyl-CoA reductase (also known as long-chain-fatty-acyl-CoA reductase) LuxC proteins. The channelling of fatty acids into the fatty aldehyde substrate for the bacterial bioluminescence reaction is catalysed by a fatty acid reductase multienzyme complex, which channels fatty acids through the thioesterase (LuxD), synthetase (LuxE) and reductase (LuxC) components [(PUBMED:9128139), (PUBMED:2030669)].
GO process:oxidation-reduction process (GO:0055114), bioluminescence (GO:0008218)
GO function:acyl-CoA dehydrogenase activity (GO:0003995)
