ENZYME entry: EC 3.4.11.26

Accepted Name
intermediate cleaving peptidase 55
Reaction catalysed
The enzyme cleaves the 36-Pro-Pro-37 bond of cysteine desulfurase (EC 2.8.1.7) removing three amino acid residues (Tyr-Ser-Pro) from the N-terminus after cleavage by mitochondrial processing peptidase
Comment(s)
  • Icp55 removes the destabilizing N-terminal amino acid residues that are left after cleavage by the mitochondrial processing peptidase, leading to the stabilization of the substrate.
  • The enzyme can remove single amino acids or a short peptide, as in the case of cysteine desulfurase (EC 2.8.1.7), where three amino acids are removed.
