ISOLATION FROM BEEF PANCREAS OF CRYSTALLINE TRYPSINOGEN, TRYPSIN, A TRYPSIN INHIBITOR, AND AN INHIBITOR-TRYPSIN COMPOUND [PDF]
Methods are described for the isolation and crystallization of trypsinogen, trypsin, a substance which inhibits trypsin, and an inhibitor-trypsin compound. Analyses and some of the properties of these compounds are given.

HUMAN SEMINAL TRYPSIN INHIBITORS [PDF]
Summary. The presence of trypsin inhibitors in human seminal plasma was demonstrated, and their effect on the acrosomal trypsin-like enzyme (TLE), as well as on other proteolytic enzymes, was studied. Two inhibitor fractions with approximate molecular weights of 11,500 and 4000 were obtained by gel filtration.

Differential in vitro and in vivo effect of barley cysteine and serine protease inhibitors on phytopathogenic microorganisms [PDF]
Protease inhibitors from plants have been involved in defence mechanisms against pests and pathogens. Phytocystatins and trypsin/α-amylase inhibitors are two of the best characterized protease inhibitor families in plants.

Engineering trypsin for inhibitor resistance [PDF]
AbstractThe development of effective protease therapeutics requires that the proteases be more resistant to naturally occurring inhibitors while maintaining catalytic activity. A key step in developing inhibitor resistance is the identification of key residues in protease‐inhibitor interaction. Given that majority of the protease therapeutics currently

Legumes are an important source of protein in many developing countries. However this protein is not readily available because of antinutrients. Farmers are being encouraged to grow bambara groundnut to meet food sufficiency, hence information on the ...

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

Calorimetry of Some Trypsin-Trypsin Inhibitor Reactions
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

Improving Digestibility of Soy Flour by Reducing Disulfide Bonds with Thioredoxin [PDF]
The Kunitz trypsin inhibitor (KTI) and the Bowman−Birk inhibitor (BBI) of trypsin and chymotrypsin contain disulfide bonds. Glycinin, the major storage protein in soybeans also contains disulfide bonds.

Tyrosine sulfation of human trypsin steers S2' subsite selectivity towards basic amino acids. [PDF]
Human cationic and anionic trypsins are sulfated on Tyr154, a residue which helps to shape the prime side substrate-binding subsites. Here, we used phage display technology to assess the significance of tyrosine sulfation for the specificity of human ...
