RT   membrane vesicles as a receptor of Bacillus thuringiensis crylac delta-
RT   endotoxin.";
RL   Curr. Microbiol. 43:255-259(2001).
CC   -!- FUNCTION: Acts as a receptor for B.thuringiensis Cry1Ac delta-
CC       endotoxin. {ECO:0000269|PubMed:11683359}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Release of an N-terminal amino acid, Xaa-|-Yaa- from a
CC         peptide, amide or arylamide. Xaa is preferably Ala, but may be most
CC         amino acids including Pro (slow action). When a terminal hydrophobic
CC         residue is followed by a prolyl residue, the two may be released as
CC         an intact Xaa-Pro dipeptide.; EC=3.4.11.2;
CC         Evidence={ECO:0000269|PubMed:11683359};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC   -!- ACTIVITY REGULATION: Inhibited by the zinc-chelators 2,2-dipyridyl and
CC       1,10-phenanthroline. {ECO:0000269|PubMed:11683359}.
CC   -!- SIMILARITY: Belongs to the peptidase M1 family. {ECO:0000305}.
