Molecular Formula | C31H38N4O7S
|
Molar Mass | 610.72102 |
Appearance | Liquid |
Color | white |
Storage Condition | -20°C |
MDL | MFCD00081476 |
Use | It can specifically degrade from the C end of the peptide chain one by one, releasing a class of peptide chain exonuclease with free amino acids. Carboxypeptidase B only hydrolyzes the peptide bond with basic amino acids (such as arginine and lysine) as the C- terminal residue. |

EC 3.4.17.2 - Introduction
Carboxypeptidase B catalyzes hydrolysis of the basic amino acids lysine, arginine and ornithine from the C- terminal end of polypeptides. The molecular weight is 34,500 daltons, the pH optimum is 7.9, and the pI is 6.0. Carboxypeptidase B is competitively inhibited by arginine, lysine and ornithine. The enzyme is not inhibited by di-isopropylfluorophosphate (DFP), but it is inhibited by metal chelating agents, e.g., 1,10-phenanthroline.
