CC   -!- FUNCTION: Might be efficient in the degradation of transiently
CC       denatured and unfolded proteins which accumulate in the periplasm
CC       following stress conditions. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Acts on substrates that are at least partially unfolded. The
CC         cleavage site P1 residue is normally between a pair of hydrophobic
CC         residues, such as Val-|-Val.; EC=3.4.21.107;
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the peptidase S1C family. {ECO:0000305}.
