Abstract:
Chloroplast proteases play an essential role in orchestrating chloroplast biogenesis and maintaining the homeostasis of diverse metabolic pathways within these organelles, including photosynthesis, amino acid biosynthesis, and stress response regulation. Recent advances in chloroplast proteostasis research have systematically elucidated the physiological functions of key protease families (e.g., FtsH, Deg, and CLP complexes) within chloroplast. This review systematically integrates cutting-edge advances in the physiological functions of chloroplast proteolytic systems, including protein maturation, protein quantity control, protein quality control, and amino acid recovery, and provide a fresh perspective to understand proteases in chloroplasts. According to the latest research progress, the key remaining problems and future research directions in this field are highlighted.

Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
