OX NCBI_TaxID=29058; RN [1] RP PROTEIN SEQUENCE, FUNCTION, CATALYTIC ACTIVITY, AND ACTIVITY REGULATION. RC TISSUE=Larval midgut; RX PubMed=11683359; DOI=10.1007/s002840010297; RA Ingle S.S., Trivedi N., Prasad R., Kuruvilla J., Rao K.K., Chhatpar H.S.; RT "Aminopeptidase-N from the Helicoverpa armigera (Hubner) brush border 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}.
