[Changes in the model membrane structure induced by ribonuclease and lysozyme studied by the fluorescent probe technique].
Using fluorescent probes DSM and DSP-12, the effect of ribonuclease and lysozyme on the structural state of liposomes composed of phosphatidylcholine and diphosphatidylglycerol was studied. A correlation between the changes in probe quantum yield and the amount of protein-bound lipids was established. It is assumed that the formation of protein-lipid complexes increases the packing density of lipids and restricts their mobility. As the content of diphosphatidylglycerol in the lipid bilayer increases, the condensing effect of proteins becomes more pronounced.
