Function
[PSA_MYCTA] Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. [BPA_MYCTO] Interacts with the core proteasome alpha-subunit (PrcA) through its C-terminal hydrophobic-tyrosine-X motif (HbYX motif). Interaction of Bpa with the proteasome stimulates proteosomal peptidase and casein degradation activity, which suggests Bpa could play a role in the removal of non-native or damaged proteins by influencing the conformation of the proteasome complex upon interaction. Can inhibit degradation of Pup-tagged substrates in vitro by competing with Mpa for association with the proteasome.[UniProtKB:P9WKX3] [PSB_MYCTA] Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation.
