DESCRIPTION
Recombinant Carboxypeptidase B
Carboxypeptidase?B?catalyzes?hydrolysis?of?the?basic?amino?acids?lysine,?arginine?and?histidine?from?the?
C-terminal?end?of?polypeptides.?The?molecular?weight?is?34,500?daltons,?the?pH?optimum?is?8.0,?and?pI?is?
6.0.?Carboxypeptidase?B?is?competitively?inhibited?by?arginine?and?lysine.?The?enzyme?is?also?inhibited?by?
metal?chelating?agents,?e.g.,?EDTA.?Recombinant?Carboxypeptidase?B?(EC?3.4.17.2)?is?expressed?in?E.Coli?
and?purified?by?high?pressure?liquid?chromatography.?There?is?no?trace?of?other?enzyme?(such?as?
carboxypeptidase?A?and?chymotrypsin)?activity.?No?protease?inhibitors?such?as?PMSF?are?present?in?the?
preparation.
