3h4p is a 28 chain structure with sequence from Methanocaldococcus jannaschii. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
PSA_METJA Component of the proteasome core, a large protease complex with broad specificity involved in protein degradation. The M.jannaschii proteasome is able to cleave oligopeptides after Glu, Asp, Tyr, Phe, Trp, slightly after Arg, but not after Ala. Thus, displays caspase-like and chymotrypsin-like activities and low level of trypsin-like activity.[HAMAP-Rule:MF_00289][1]
