This family consists of several bacterial 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 [1].
