TPPII
PFAM accession number:PF12580
Interpro abstract (IPR022229):

This entry represents a region of approximately 190 amino acids in length and is found in association with . The members are serine peptidases belonging to MEROPS peptidase family S8A, tripeptidyl peptidase II (TPPII), clan SB. They are a crucial component of the proteolytic cascade acting downstream of the 26S proteasome in the ubiquitin-proteasome pathway. It is an amino peptidase belonging to the subtilase family removing tripeptides from the free N terminus of oligopeptides.
