摘要：

The photosynthetic oxygen-evolving activity of the photosystem 2 complex, prepared from spinach, was labile when the complex was exposed to high-salt conditions under which the extrinsic proteins were dissociated from the complex. Glycinebetaine prevented the dissociation of the 18-kDa and the 23-kDa extrinsic proteins from the photosystem 2 complex in the presence of 1 M NaCl. It also prevented the dissociation of the 33-kDa extrinsic protein from the complex in the presence of 1 M MgCl2 or 1 M CaCl2. The oxygen-evolving activity of the photosystem 2 complex was stabilized by glycinebetaine when the complex was subjected to treatment with NaCl and MgCl2.
