CC -!- FUNCTION: Component of the proteasome, a multicatalytic proteinase
CC complex which is characterized by its ability to cleave peptides with
CC Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or
CC slightly basic pH. The proteasome has an ATP-dependent proteolytic
CC activity. {ECO:0000256|RuleBase:RU004203}.
