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.

ADVANTAGES
?
Animal?origin?free:YaxinBio?recombinant?carboxypeptidase?B?belongs?to?the?AOF?level?3.?Level?3?
recombinant?carboxypeptidases?B?eliminate?the?risk?of?virus?presence,?or?of?any?other?potential?
adventitious?agents?found?in?animal-derived?carboxypeptitase?B
Stable:A?sterile?recombinant?carboxypeptidase?B?lyophilized?powder?eliminates?the?risk?of?contamination?
and?decreases?the?chances?of?activity?loss?in?the?process?of?transport?and?storage.?It?is also?very?convenient?for?transport?and?storage.?
?
High?purity:
?
1. Recombinant?carboxypeptidase?B?provides?increased?specificity?and?eliminates?contaminating?activities
?found?in?enzymes?with?lower?purity?level.?
2. No?other?contaminating?proteases?such?as?chymotrypsin?and?carboxypeptidase?A.?Less?than?10ppm?of?
recombinant?trypsin.?
3. One?single?main?band?at?35kD?by?SDS-PAGE.
