ID   3.4.22.40
DE   bleomycin hydrolase.
AN   aminopeptidase C (Lactococcus lactis).
CA   Inactivates bleomycin B2 (a cytotoxic glycometallopeptide) by hydrolysis
CA   of a carboxyamide bond of beta-aminoalanine, but also shows general
CA   aminopeptidase activity. The specificity varies somewhat with source,
CA   but amino acid arylamides of Met, Leu and Ala are preferred.
CC   -!- The active sites are on the walls of a central channel through the
CC       molecule, and access of substrate molecules to them is obstructed by
CC       this and by the C-terminus of each polypeptide chain.
CC   -!- Bleomycin can scarcely be the natural substrate, and there are
CC       reports of limited endopeptidase activity.
CC   -!- Known from bacteria as well as eukaryotic organisms.
CC   -!- Hydrolase H from chicken muscle has many similarities to bleomycin
CC       hydrolase, but hydrolyzes Ph-CO-Arg-2-naphthylamine as well as
CC       aminopeptidase substrates.
CC   -!- Belongs to peptidase family C1.
