Research Abstract

To avoid photoinhibition (light-dependent irreversible inactivation of Photosystem II (PSII)), an efficient degradation of D1 protein in the repair cycle of PSII is important. In this study, we focused on the function of proteases that are involved in D1 protein degradation, our results revealed the in vivo cooperative function between the FtsH-dependent processive degradation of D1 and the Deg-dependent cleavage of D1.
