Measurement of the Proteinase Inhibitors of the Bovine Pancreas by Radioimmunoassay [PDF]

open access: yes, 1976
Bovine pancreas contains two polypeptide trypsin inhibitors that are not homologous and differ in their inhibitory activity towards chymotrypsin, kallikrein, elastase, and other serine proteinases. The Kunitz inhibitor and the Kazal inhibitor are present

Trypsin Inhibitor in Wholewheat Flour [PDF]

open access: yesNature, 1961
PRELIMINARY work on a trypsin inhibitor in wholewheat flour was reported by Shyamala1. A crude concentrate containing the trypsin inhibitor was prepared by the ‘ammonium sulphate’ method of Borchers et al.2 modified by Lyman3 as follows:

Proteolytic processing and activation of Clostridium perfringens epsilon toxin by caprine small intestinal contents. [PDF]

open access: yes, 2014
Epsilon toxin (ETX), a pore-forming toxin produced by type B and D strains of Clostridium perfringens, mediates severe enterotoxemia in livestock and possibly plays a role in human disease.

The occurrence of a trypsin inhibitor in brain [PDF]

open access: yesBiochemical Journal, 1967
1. The tryptic hydrolysis of benzoyl-dl-argininyl-beta-naphthylamide is inhibited by homogenates of human and ox brain. 2. The inhibitor is associated primarily with the membranous portion of the particulate matter, and is not found in the 90000g supernatant fraction. 3. The reaction of the inhibitor with trypsin is rapid. 4.

Trypsin inhibition by macrocyclic and open-chain variants of the squash inhibitor MCoTI-II [PDF]

open access: yes, 2005
MCoTl-I and MCoTl-II from the seeds of Momordica cochinchinensis are inhibitors of trypsin-like proteases and the only known members of the large family of squash inhibitors that are cyclic and contain an additional loop connecting the amino- and the ...

Laura: Soybean variety lacking Kunitz trypsin inhibitor [PDF]

open access: yesSelekcija i Semenarstvo, 2010
Grain of conventional soybean varieties requires heat processing to break down trypsin inhibitor's activity before using as food or animal feed. At the same time, protein denaturation and other qualitative changes occur in soybean grain, especially if ...

Calorimetry of Some Trypsin-Trypsin Inhibitor Reactions

open access: yesJournal of Biological Chemistry, 1972
The heats of reaction of trypsin with soybean (Kunitz), ovomucoid, and lima bean inhibitors have been measured at pH 5.0 and 10° and 25°. All the reactions were endothermic, with ΔH ranging from 8.6 Cal per mole for the lima bean inhibitor to 15.3 Cal per mole for the soybean inhibitor. Equilibrium constants for the association were calculated from the

Identification of Kunitz inhibitor from Cassia obtusifolia L. and its inhibitory effect against Pieris rapae proteases

open access: yes浙江大学学报. 农业与生命科学版, 2008
A trypsin inhibitor from Cassia obtusifolia seeds, a well known Chinese herb, was isolated to apparent homogeneity by a combination of distilled water extraction, ammonium sulfate precipitation, Sepharose 4B-trypsin affinity and Sephadex G-75 ...
