CC   -!- FUNCTION: ATP-dependent serine protease that mediates the selective
CC       degradation of misfolded and unassembled polypeptides in the
CC       peroxisomal matrix (By similarity). Necessary for type 2 peroxisome
CC       targeting signal (PTS2)-containing protein processing and facilitates
CC       peroxisome matrix protein import. {ECO:0000255|HAMAP-Rule:MF_03121,
CC       ECO:0000269|PubMed:19748917}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of proteins in presence of ATP.; EC=3.4.21.53;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03121};
CC   -!- SUBCELLULAR LOCATION: Peroxisome matrix {ECO:0000255|HAMAP-
CC       Rule:MF_03121, ECO:0000269|PubMed:19329564}.
CC   -!- SIMILARITY: Belongs to the peptidase S16 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03121}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAO00734.1; Type=Erroneous initiation; Evidence={ECO:0000305};
