CC -!- FUNCTION: Protease with a carboxypeptidase B-like function involved in
CC the C-terminal processing of the lysine and arginine residues from the
CC precursors of K1, K2 and K28 killer toxins and a-factor (mating
CC pheromone). Involved in the programmed cell death caused by defective
CC N-glycosylation and contributes also to the active cell death program
CC induced by acetic acid stress or during chronological aging. Promotes
CC cell fusion by proteolytically processing substrates that act in
CC parallel to PRM1 as an alternative fusion machine, as cell wall
CC components, or both (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Preferential release of a C-terminal arginine or lysine
CC residue.; EC=3.4.16.6;
CC -!- SUBCELLULAR LOCATION: Golgi apparatus, trans-Golgi network membrane
CC {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase S10 family. {ECO:0000305}.
