LITERATURE
analysis
-
application of CPY as sensing element in a biosensor for the direct detection of ochratoxin A and comparison with thermolysin. Thermolysin and CPY both exhibit an optimal activity under the conditions 35 min cross-linking time, working pH of 7 and temperature of 25°C and exhibit comparable analytical performances in the biosensor. Ochratoxin A concentrations can be determined without pretreatment of the sample and no matrix effect is observed
molecular biology
a method is described exploiting the possibility to attach different reactive handles to their C-termini using a reaction catalyzed by CPY. It is possible to attach pairs of reaction handles which can react with each other to each of the peptides to be coupled. In a second step, the two modified peptides can be linked together by a chemical reaction, such as an oxime-forming reaction or a copper(I) catalyzed (2+3)-cycloaddition reaction of an azide with an alkyne
nutrition
-
MpiCP-1 suppresses and reverses the development of the bitterness taste that results from the pepsin hydrolysis of soybean protein by releasing mainly hydrophobic amino acids from the C-termini of the bitter components
synthesis
synthesis of CPY in Pichia pastoris as procarboxypeptidase Y with a yield of about 605 mg/l in shake-flasks after 168 h induction with 1 % (v/v) methanol. This precursor is cleaved by endogenous proteinases of Pichia pastoris and released into the fermentation broth as active carboxypeptidase Y within 2 weeks at 10°C. The recombinant enzyme is optimally active at 30°C and pH 6.0, with an optimal activity of about 305 U/mg
