Protein and lipid interactions driving molecular mechanisms of in meso crystallization.

ABSTRACT: The recent advances in the in meso crystallization technique for the structural characterization of G-protein coupled receptor (GPCR) proteins have established the usefulness of the lipidic-cubic phases (LCPs) in the field of crystallography of membrane proteins. It is surprising that despite the success of the approach, the molecular mechanisms of the in meso method are still not well understood. Therefore, the approach must rely on extensive screening for a suitable protein construct, for host and additive lipids, and for the appropriate precipitants and temperature. To shed light on the in meso crystallization mechanisms, we used extensive coarse-grained molecular dynamics simulations to study, in molecular detail, LCPs under different conditions (compositions and temperatures relevant
