Introduction
in Mycobacterium Tuberculosis is an ACSVL (Acyl-CoA synthetases very long) peripheral membrane protein. ACS proteins activate lipids and fatty acids before going into metabolic pathways. FadD13 is soluble unlike other ACSVL proteins. FadD13 contains a hydrophobic tunnel for fatty acids to bind to, as well as an arginine rich lid loop that binds to the cell membrane. The binding of ATP causes structural changes promoting the binding of the hydrophobic substrates. Formation of an acyl-adenylate intermediate induces a 140 degree rotation of the small domain and binding of CoA for production of the final product, a fatty acyl-CoA thioester.
