Stabilization by glycinebetaine of photosynthetic oxygen evolution by thylakoid membranes from Synechococcus PCC7002.
Active thylakoid membranes were prepared from Synechococcus PCC7002 in a medium that contained glycinebetaine. The oxygen-evolving activity of photosystem II of these thylakoid membranes was enhanced and stabilized by the presence of glycinebetaine. The heat stability of the oxygen-evolving activity of the thylakoid membranes was also enhanced by glycinebetaine.
