Crystal Structure of Tripeptidyl peptidase (2d5l)
Tripeptidyl peptidase (TPP) is an enzyme which cleaves N-terminal tripeptides from polypeptides. TPP-I functions in lysosomes, TPP-II is part of the ubiquitin-proteasome pathway. The images at the left and at the right correspond to one representative TPP, i.e. the crystal structure of Pro-Tripeptidyl peptidase-IV from Porphyromonas gingivalis (2d5l).
