| physiological function | ICP55 is responsible for the removal of single N-terminal amino acids, and its action explained the -3 arginine processing motif of a number of mitochondrial proteins. ICP55 also removes single amino acids from mitochondrial proteins known to be cleaved at nonconserved arginine sites. Disruption of ICP55 alters mitochondrial protein stability in vitro and changes the protein turnover rate of selected proteins in vivo | Arabidopsis thaliana |
