| Comment | This bacterial family of Acyl transferases (ACT or myristoyl-acp-specific thioesterases) catalyses the first step in the bioluminescent fatty acid reductase system, which is required for aldehyde biosynthesis. This enzyme belongs to the LuxD family. Together with acyl-protein synthetase (LuxE) and reductase (LuxC), it belongs to a multienzyme complex. This complex channels activated fatty acids into the aldehyde substrate for the luciferase-catalyzed bacterial bioluminescence reaction. The C-terminal region of LuxD interacts with LuxE to causes a conformational change. LuxD has a calculated M(r) of 34,384 and comprises 305 aa residues. Induction of luminescence only occurs at high cell density. Some bacteria have N-acylhomoserine lactone autoinducers for luminescence.
