DBG's Eduard Strasburger Workshop - Co- and posttranslational control in chloroplasts

Photosynthesis must be dynamically regulated in response to environmental conditions to prevent photoinhibition and photodamage to the photosystems. Various post-translational modifications of proteins are known to play important roles in modulating photosynthetic efficiency during plant acclimation responses. Alongside phosphorylation and dithiol-based modifications, acetylation of amino groups within proteins is a major post-translational modification, particularly abundant on proteins involved in photosynthesis. The role of protein acetylation in photosynthesis regulation is only beginning to be uncovered. Additionally, very little is known about the interplay and kinetics of different post-translational modifications. Here, I will present a global overview of light-dependent modifications in chloroplasts, with a particular focus on lysine and N-terminal acetylation in conjunction with phosphorylation.
