Using fluorescent probe 4-(dimethylaminostyryl)-1-methylpiridine n-tol
uenesulfonate (DSM) the effect of ribonuslease and lysozyme on the str
ucture of liposomes composed of phosphatidylcholine and diphosphatidyl
glycerol has been studied. An analysis of DSM spectra contour has been
carried out and parameters of inhomogeneous broadening(has been estim
ated. Polarity of the probe surroundings was found to decrease upon li
pid-protein complexes formation.
