Alternative name(s):
Bleomycin hydrolase

Gene names

Name:

pepC

Organism

Lactobacillus delbrueckii subsp. lactis

Taxonomic identifier

29397 [NCBI]

Taxonomic lineage

Bacteria › Firmicutes › Lactobacillales › Lactobacillaceae › Lactobacillus

Protein attributes

Sequence length	449 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Catalytic activity	Inactivates bleomycin B2 (a cytotoxic glycometallopeptide) by hydrolysis of a carboxyamide bond of beta-aminoalanine, but also shows general aminopeptidase activity. The specificity varies somewhat with source, but amino acid arylamides of Met, Leu and Ala are preferred.
Subunit structure	Homohexamer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the peptidase C1 family.
