3c91 is a 28 chain structure with sequence from Thermoplasma acidophilum. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
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.[1]
