A possible route for the release of fatty acid from fatty acid-binding protein.

Abstract

A simulation of the release of fatty acid from intestinal fatty acid-binding protein was attempted, starting with the crystallographic model and using molecular-dynamic processes at different temperatures. The release of the ligand was observed only at high temperature, which perhaps makes the process unreliable in detail. Nevertheless, the overall behaviour of the protein, also confirmed by the simulation performed at room temperature, strongly supports the idea that the fatty acid leaves the protein through an opening formed by alpha-helix II and turns beta C-beta D and beta E-beta F. Additionally, it suggests a role for the lack of hydrogen bonds between the main chains of beta-strands D and E: this feature, observed in all the protein structures of this family which have currently been determined, seems to provide the structure with great flexibility, allowing the barrel to open and close without disruption of the hydrogen-bond network.
