SRCPB01
Description
Animal components free carboxypeptidase B for? Protein structure and sequence analysis
?
DESCRIPTION
?
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

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.
