Cb. Lee et al., STABILIZATION BY GLYCINEBETAINE OF PHOTOSYNTHETIC OXYGEN EVOLUTION BYTHYLAKOID MEMBRANES FROM SYNECHOCOCCUS PCC7002, Molecules and cells, 7(2), 1997, pp. 296-299
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 stabil
ized by the presence of glycinebetaine. The heat stability of the oxyg
en evolving activity of the thylakoid membranes was also enhanced by g
lycinebetaine.
