Trypsinis a proteolytic enzyme produced in the pancreas in the precursor form of inactive trypsinogen. Trypsinogen is converted to trypsin in the duodenum by enterokinase. Trypsin is present in the stool of young children but amounts lessen in older children and adults as a result of intestinal ...
in the digestive systems of invertebrates, it became the most abundant proteinase. As in vertebrates, invertebrate trypsin is also present in several forms (isoenzymes). Its physiological importance
Here we report that trypsin-binding IgG (TbIgG) is present in 80% of CF patients and in 30% of their mothers, but not in 97% of normal controls or in other relatives of CF patients. Experimental evidence supports the antibody nature of TbIgG, which is presumably produced against the ...
Trypsin inhibitors in a selection of grain legume seeds from different species and cultivars were studied. The results showed that trypsin inhibition content ranged from negligible in Lupinus spp. to very high in Glycine max. Although there is variation among cultivars, generally the highest TIU mg...
Early trypsin is a female-specific protease present in the Aedes aegypti midgut during the first hours after ingestion of a blood meal. Early trypsin gene expression was studied by Northern blot analysis. The early trypsin mRNA, absent in larvae, pupae and newly emerged females, reaches ...
This trypsin-like immunoreactivity was shown in the Paneth cells at their normal localization at the basis of the crypts of Lieberkühn and also in Paneth cells of metaplastic areas in gastric mucosa. This original finding is a further indication of a resemblance between Paneth and ...
PI and PAI are present mainly in milk serum (whey), and their activity is affected mainly by pH fluctuation and heat treatment. Inhibitors of PL and PAs have been studied as one potential means of controlling PL-related activities. Numerous researchers have reported the presence of protease ...

The metabolism of P450 enzymes, particularly Cyt P450 enzymes, has a major role in detoxifying herbicides and is one chief cellular mechanisms found in plants to confer resistance against applied herbicides or pesticides. Our present ... Q Mahmood,M Bilal,S Jan 被引量: 16发表: 2014年 envB ...
The activity of trypsin is decreased when acidic residues are present on either side of a susceptible bond. If proline is at the carboxylic side of lysine or arginine, the bond is almost completely resistant to cleavage by trypsin. Trypsin is often used for in-gel digestion. In this ...
