[Interaction of the glycoprotein from the Bacillus pumilis cell wall with liposomes].
The methods of centrifugation and gel-filtration on Sephadexes G-50 and G-150 were used to study the interaction of Bacillus pumilis cell wall glycoprotein component having the molecular weight of 50 kDa (GP-50) with lyposomes from bacterial lipids. GP-50 is shown to sorb on such liposomes and disturb their barrier properties inducing yield of low-molecular label. GP-50 exerts no effect on properties of liposomes from egg lecithin. Electrostatic forces are supposed to play a decisive role in initial acts of GP-50 interactions with lipid phase of microbial envelopes.
