Arrangement of Lipids and Proteins in Sarcoplasmic Reticulum Membranes

3 Arrangement of Lipids and Proteins in Sarcoplasmic Reticulum Membranes 

The low lipid-protein ratio of 0.5 together with the size of the sarcoplasmic vesicles implies that only approximately 30% of their membranes can be occupied by a regular lipid bilayer structure. Consequently, a large fraction of the membrane protein must interrupt the lipid bilayer and reach throughlt. The fact that only one polypeptide chain constitutes the structural unit of the calcium transport protein strong-
