== Function ==
[https://www.uniprot.org/uniprot/PSB1_RHOER PSB1_RHOER] Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The R.erythropolis proteasomes are able to cleave oligopeptides after Tyr, Phe and Leu, very poorly after Arg but not after Glu. Thus, displays chymotrypsin-like activity, low trypsin-like activity but no caspase-like activity.[HAMAP-Rule:MF_02113]<ref>PMID:7583123</ref> <ref>PMID:9000518</ref>
