The occurrence of a trypsin inhibitor in brain [PDF]
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.

The Reactive Site of Trypsin Inhibitors
Virgin soybean trypsin inhibitor has 1 NH2-terminal aspartic acid or asparagine residue and no COOH-terminal residues that can be released by carboxypeptidase B. Upon incubation with 1 mole % of trypsin for 24 hours at pH 3.75, virgin inhibitor is converted to a modified inhibitor which has 2 NH2 terminals aspartic acid or asparagine and isoleucine ...

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

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

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.

Pancreatic secretory trypsin inhibitor: More than a trypsin inhibitor
Kazal-type serine protease inhibitor is one of the most important and widely distributed protease inhibitor families. Pancreatic secretory trypsin inhibitor (PSTI), also known as serine protease inhibitor Kazal type I(SPINK1), binds rapidly to trypsin, inhibits its activity and is likely to protect the pancreas from prematurely activated trypsinogen ...

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.
