This study shows that the flexible regions of protein D1 that protrude into the lumen can penetrate through the three side-openings of Deg1 and reach its internal proteolytic sites. This mode of action, facilitating cooperation between proteases on both sides of the thylakoid membranes, should be applicable to the degradation | Lumenal exposed regions of the D1 protein of PSII are long enough to be degraded by the chloroplast Deg1 protease.

PSB33 is predominantly located in non-appressed thylakoid regions and dynamically associates with a thylakoid protein complex in a light-dependent manner. Moreover, plants lacking PSB33 show an accelerated D1 protein degradation in nocturnal periods, and show severely stunted growth when challenged with fluctuating light. | PSB33 sustains photosystem II D1 protein under fluctuating light conditions.

The initiation of (1)O2 signaling in grana margins depends on EX1 and the ATP-dependent zinc metalloprotease FtsH. As FtsH cleaves also the D1 protein during the disassembly of damaged PSII, EX1- and (1)O2-mediated signaling seems to be not only spatially but also functionally associated with the repair of PSII | Singlet oxygen- and EXECUTER1-mediated signaling is initiated in grana margins and depends on the protease FtsH2.
