Crystal structure of rat carnitine palmitoyltransferase 2 in complex with r-3-(hexadecanoylamino)-4-(trimethylazaniumyl)butanoate
Overview
The mitochondrial membrane-associated carnitine palmitoyltransferase system is a validated target for the treatment of type 2 diabetes mellitus. To further facilitate structure-based drug discovery, we determined the crystal structure of rat CPT-2 (rCPT-2) in complex with the substrate analogue palmitoyl-aminocarnitine at 1.8A resolution. Biochemical analyses revealed a strong effect of this compound on rCPT-2 activity and stability. Using a computational approach we examined the membrane association of rCPT-2. The protein interacts with the membrane as a functional monomer and the calculations confirm the presence of a membrane association domain that consists of layers of hydrophobic and positively charged residues.
