The ability for FadD13 to transport and activate fatty acids of the maximum tested length C26, lies in it being a peripheral membrane protein. FadD13 is attached to the membrane via electrostatic interactions in the N-terminal domain. Of importance in the region is the arginine rich lid-loop which serves to block the transport of fatty acids into the enzyme. Once the lid-loop is opened, fatty acids may be pulled from the membrane into a hydrophobic tunnel, which is the main structural component by which fatty acids are transported from the membrane into the cell. Negatively charged residues at the active site of FadD13 are the driving factor in the attraction of the fatty acid from the membrane through the hydrophobic tunnel of the enzyme. | The ability for FadD13 to transport and activate fatty acids of the maximum tested length C26, lies in it being a peripheral membrane protein.
