intermediate cleaving peptidase 55 EC#: 3.4.11.26; ChemWhat Code: 1380306

Product Name intermediate cleaving peptidase 55
Example Structure Example Structure of intermediate cleaving peptidase 55 EC#: 3.4.11.26
Synonyms
EC Number 3.4.11.26
CAS Registry Number
Comments Icp55 removes the destabilizing N-terminal amino acid residues that are left after cleavage by the mitochondrial processing peptidase, leading to the stabilisation 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.
Cofactor
History
Reactions 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.
