== Function ==
[https://www.uniprot.org/uniprot/PSA_THEAC PSA_THEAC] Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The T.acidophilum proteasome is able to cleave oligopeptides after Tyr, Leu, Phe, and to a lesser extent after Glu and Arg. Thus, displays chymotrypsin-like activity and low level of caspase-like and trypsin-like activities.<ref>PMID:8999862</ref>
