Ubiquitin-dependent chloroplast-associated protein degradation in plants (Science) ($)

The fidelity of the chloroplast proteome is a major factor in the functional efficiency of photosynthesis. A RING-type ubiquitin E3 ligase, SP1, is an outer envelope localized protein in the chloroplast which ubiquitinates the protein import translocases (TOC proteins) and thus target them to 26S mediated…
