CC   -!- FUNCTION: May play a specific role in the degradation of signal
CC       peptides after they are released from precursor forms of secreted
CC       proteins. Can cleave N-acetyl-L-Ala(4) (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of oligopeptides, with broad specificity. Gly or
CC         Ala commonly occur as P1 or P1' residues, but more distant residues
CC         are also important, as is shown by the fact that Z-Gly-Pro-Gly-|-Gly-
CC         Pro-Ala is cleaved, but not Z-(Gly)(5).; EC=3.4.24.70;
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion. {ECO:0000250};
CC   -!- SIMILARITY: Belongs to the peptidase M3 family. {ECO:0000305}.
