Carboxypeptidase M/CPM Protein, Human (HEK293, His)

Carboxypeptidase M Protein, Human (HEK293, His) is an approximately 55.0 kDa Carboxypeptidase M protein with a His-flag. Carboxypeptidase M is a membrane-bound arginine/lysine carboxypeptidase enzyme belongs to the carboxypeptidases family^[1].

Carboxypeptidase M is a membrane-bound arginine/lysine carboxypeptidase enzyme, cleaves C-terminal basic amino acids with a neutral pH optimum^[1].
  Carboxypeptidase M belongs to the carboxypeptidases family. Carboxypeptidase M is widely distributed in a variety of tissues and cells, and it constitutively expresses in an active form at the surface of specialized cells and tissues in the human body^[2].
Carboxypeptidase M plays an important role in the physiological processes of blood coagulation/fibrinolysis, inflammation, food digestion and pro-hormone and neuropeptide processing^[3].

Measured by its ability to release L-arginine from Benzoyl-Ala-Arg, with detection of the arginine amino group by o-phthaldialdehyde. The specific activity is 187829.19 pmol/min/μg that incubate for 10 minutes at room temperature.
