title: [Role of monovalent cations in protein-lipid interaction in chloroplast membranes].
abstract: Role of monovalent cations in chloroplast membranes was investigated using chlorophyll a as an endogenous fluorescent probe. It is found using specific membrane modification by trypsin and lipophylic polypeptide, gramicidin S, that cations cause changes in the chlorophyll microenvironment. The mechanism of these changes is suggested to be an induction of the protein conformational ability, which results in the rearrangement of their lipid environment and in the differentiation of the latter.
