Light-Dependent Translation Change of Arabidopsis psbA Correlates with RNA Structure Alterations at the Translation Initiation Region.
Title: Light-Dependent Translation Change of Arabidopsis psbA Correlates with RNA Structure Alterations at the Translation Initiation Region.
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
Title: Lumenal exposed regions of the D1 protein of PSII are long enough to be degraded by the chloroplast Deg1 protease.
Light stimulates psbA translation initiation in the context of photosystem II homeostasis in plants
Title: Multilevel effects of light on ribosome dynamics in chloroplasts program genome-wide and psbA-specific changes in translation.
LPE1 interacts with a known regulator of psbA mRNA translation HIGH CHLOROPHYLL FLUORESCENCE 173 (HCF173) and facilitates the association of HCF173 with psbA mRNA.
Title: LOW PHOTOSYNTHETIC EFFICIENCY 1 is required for light-regulated photosystem II biogenesis in Arabidopsis.
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.
Title: 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
Title: Singlet oxygen- and EXECUTER1-mediated signaling is initiated in grana margins and depends on the protease FtsH2.
Dephosphorylation of PSII subunits is required for efficient D1 degradation.
Title: Significance of the photosystem II core phosphatase PBCP for plant viability and protein repair in thylakoid membranes.
C-terminal processing of reaction center protein D1 is essential for the function and assembly of photosystem II in Arabidopsis.
Title: C-terminal processing of reaction center protein D1 is essential for the function and assembly of photosystem II in Arabidopsis.
HCF244 was identified by coexpression analysis of HCF173, which encodes a protein that is also necessary for psbA translational initiation and in addition for stabilization of this messenger RNA.
Title: The atypical short-chain dehydrogenases HCF173 and HCF244 are jointly involved in translational initiation of the psbA mRNA of Arabidopsis.
These data demonstrate in vivo cooperative degradation of D1, in which Deg cleavage assists FtsH processive degradation under photoinhibitory conditions.
