| Research Abstract |
We found that a specific sequence in a chloroplast protein, chlorophyllide a oxygenase, is essential in the turnover of this protein. This sequence is most likely a degron for the chloroplast Clp protease. We obtained evidence for the presence of similar degrons in the other chloroplast proteins, indicating that the protein turnover mechanism is rather general in the chloroplast.
