CC   -!- FUNCTION: Degrades oligopeptides in a sequential manner. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase S41B family. {ECO:0000305}.
CC   -!- CAUTION: Tricorn seems to be split into two ORFs in S.tokodaii, encoded
CC       on opposite strands and separated by approximately 279 kb.
CC       {ECO:0000305}.
