Bleomycin hydrolase (BMH) is a cytoplasmic cysteine peptidase that is highly conserved through evolution. Its biological function is hydrolysis of the reactive electrophile homocysteine thiolactone.^[8] Another of its activities is metabolic inactivation of the glycopeptide bleomycin (BLM), an essential component of combination chemotherapy regimens for cancer. The protein contains the signature active site residues of the cysteine protease papain superfamily.^[7]
