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.

Trypsin inhibitors in turnip (Brassica rapa L.) seeds
A method of trypsin inhibitors isolation from turnip seeds is described. Inhibitors were extracted with 0.01 N HCI, concentrated by salting out with ammonium sulfate, and purified using ion-exchange chromatography on Sp-Sephadex C-25, QAE-Sephadex A-25 ...

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

CRYSTALLINE SOYBEAN TRYPSIN INHIBITOR [PDF]
A study has been made of the general properties of crystalline soybean trypsin inhibitor. The soy inhibitor is a stable protein of the globulin type of a molecular weight of about 24,000. Its isoelectric point is at pH 4.5. It inhibits the proteolytic action approximately of an equal weight of crystalline trypsin by combining with trypsin to form a ...

Influence of Different Genotypes on Trypsin Inhibitor Levels and Activity in Soybeans
This study describes the relationship between the two major trypsin inhibitors (TI) in soybean, i.e., the Kunitz (KTI) and Bowman-Birk (BBI) trypsin inhibitors, as well as between them and the corresponding trypsin inhibitor activity (TIA).

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

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.

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.

Combinatorial optimization of cystine-knot peptides towards high-affinity inhibitors of human matriptase-1. [PDF]
Cystine-knot miniproteins define a class of bioactive molecules with several thousand natural members. Their eponymous motif comprises a rigid structured core formed by six disulfide-connected cysteine residues, which accounts for its exceptional ...
