Mild proteasomal stress improves photosynthetic performance in Arabidopsis chloroplasts.

Nature communications - 3 Apr 2020

Abstract excerpt

The proteasome is an essential protein-degradation machinery in eukaryotic cells that controls protein turnover and thereby the biogenesis and function of cell organelles. Chloroplasts import thousands of nuclear-encoded precursor proteins from the cytosol, suggesting that the bulk of plastid proteins is transiently exposed to the cytosolic proteasome complex. Therefore, there is a cytosolic equilibrium between...
