Cathepsin X (EC 3.4.18.1, cathepsin B2, cysteine-type carboxypeptidase, cathepsin IV, cathepsin Z, acid carboxypeptidase, lysosomal carboxypeptidase B) is an enzyme.[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction
- Release of C-terminal amino acid residues with broad specificity, but lacks action on C-terminal proline. Shows weak endopeptidase activity
Cathepsin X is a lysosomal cysteine peptidase of family C1 (papain family).
