Complexes of ribonuclease, lysozyme, cytochrome c and hemoglobin with model phospholipid membranes composed of phosphatidylcholine and diphosphatidylglycerol (4:3, mol:mol) were investigated by the method of non-radiative fluorescence energy transfer. Evidence for the penetration of proteins in to the lipid bilayer interior was obtained. The size of the protein fragment incorporated into the polar membrane region was estimated.
