Stabilization by Glycinebetaine of Photosynthetic Evolution of Oxygen by Thylakoid Membranes from Synechococcus PCC7002

Chin Bum Lee, Hidenori Hayashi and Byoung Yong Moon

Abstract

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.

COVER PICTURE
Cryo-EM structure of human porphyrin transporter ABCB6 (main figure) shows that binding of hemin (inset, magenta) in concert with two glutathione molecules (cyan) primes ABCB6 for high ATP turnover (Kim et al., pp. 575-587).
