摘要：

The integrity of Photosystem II membranes isolated from chloroplast thylakoids is profoundly affected by the solute environment. Examples are given for stabilizing effects various solutes have on the binding of the 17 and 23 kDa extrinsic polypeptides under conditions conducive to their dissociation. It is concluded that these and many other solute effects on Photosystem II membranes can be accommodated readily in a concept developed by Timasheff and his coworkers according to which the responses of proteins to their solute environment are consequences of interaction preferences among the constituents of the solvent-protein-solute systems.
