Activity Regulation ACTIVITY REGULATION: The formation of the proteasomal ATPase PAN-20S proteasome complex, via the docking of the C-termini of PAN into the intersubunit pockets in the alpha-rings, triggers opening of the gate for substrate entry. Interconversion between the open-gate and close-gate conformations leads to a dynamic regulation of the 20S proteasome proteolysis activity. {ECO:0000255|HAMAP-Rule:MF_00289}.

Enzyme Function FUNCTION: Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The H.volcanii alpha1-beta-alpha2 proteasome is able to cleave oligopeptides after Tyr and thus displays chymotrypsin-like activity. {ECO:0000255|HAMAP-Rule:MF_00289, ECO:0000269|PubMed:10482525, ECO:0000269|PubMed:12486053}.
