A multi-step peptidolytic cascade for amino acid recovery in chloroplasts Academic Article uri icon


  • Plastids (including chloroplasts) are subcellular sites for a plethora of proteolytic reactions, required in functions ranging from protein biogenesis to quality control. Here we show that peptides generated from pre-protein maturation within chloroplasts of Arabidopsis thaliana are degraded to amino acids by a multi-step peptidolytic cascade consisting of oligopeptidases and aminopeptidases, effectively allowing the recovery of single amino acids within these organelles.
