Heat of reaction between trypsin and soybean trypsin inhibitor

Archives of Biochemistry and Biophysics, 1952
Abstract Calorimetric determinations of the heat of reaction between trypsin and soybean trypsin inhibitor protein indicate that ΔH for the reaction at 25 ° is 0 ± 1 kilocal./mole of trypsin reacted, if similar experiments with the inhibitor protein and bovine serum albumin are accepted as valid controls.

Energy embedding of trypsin inhibitor

Biopolymers, 1982
AbstractEnergy embedding has been shown recently to be a useful extension of the distance geometry approach to conformational calculations in the case of very small molecules and simple energy functions. This paper tests the ability of energy embedding to locate low energy conformations satisfying both weak and strong geometric constraints when the ...

TRYPSIN AND TRYPSIN INHIBITORS FROM PENAEID SHRIMP

Journal of Food Biochemistry, 2002
Trypsin inhibitors from four species of shrimp, P. vannamei, P. monodon, P. stylirostris, and P. californiensis were characterized by test tube and electrophoretic assays. Inhibitors in the four phylogenetically related species showed different inhibitory capacity and specificity for orthologous trypsins. Inhibitors from P.

Interaction of Urinary Trypsin Inhibitor, UTI68, with Bovine Trypsin

The Journal of Biochemistry, 1982
One molecule of UTI68, a trypsin inhibitor purified from urine of healthy men, inhibited four molecules of bovine trypsin. This finding suggests the formation of various complexes of UTI68 with 1 to 4 molecules of trypsin. However, SDS polyacrylamide gel electrophoresis of the reaction products of UTI68 with trypsin showed that, at molecular ratios of ...

Interrelation of the urinary trypsin inhibitor to human plasma inter-alpha-trypsin inhibitor

Clinical Biochemistry, 1973
1. Immunological investigations were conducted with specific antisera to the urinary trypsin inhibitor (UTI) and human plasma trypsin inhibitors. The results indicated that UTI is not interrelated to either α 1 -anti-trypsin or α 2 -macroglobulin, the main plasma trypsin inhibitors. UTI appears to be interrelated with inter- α -trypsin inhibitor (

The role of trypsin, trypsin inhibitor, and trypsin receptor in the onset and aggravation of pancreatitis

Journal of Gastroenterology, 2006
Trypsin activity is properly suppressed in the pancreatic acinar cells under normal conditions. A small amount of trypsinogen is converted to active trypsin and inactivated by pancreatic secretory trypsin inhibitor (PSTI), thereby preventing damage to pancreatic acinar cells as a first line of defense.

Trypsin, trypsinogen and trypsin inhibitor in human pancreatic juice

The American Journal of Medicine, 1960
Abstract 1.1. Benzoylarginine-paranitroanilide was employed as substrate in a method which permits simple, sensitive and rapid assay of trypsin. 2.2. Human pancreatic juice obtained by catheter drainage of the duct of Wirsung exhibited no spontaneous tryptic activity.

Tumour-associated trypsin inhibitor and tumour-associated trypsin

Scandinavian Journal of Clinical and Laboratory Investigation, 1990
Tumour-associated trypsin inhibitor (TATI) is a 6 kDa peptide, which is synthesized at low concentrations by several tumours and cell lines. Very high concentrations of TATI occur in mucinous ovarian tumours. Elevated levels of TATI occur in serum and urine in connection with most types of cancer at advanced stages. In mucinous ovarian cancer up to 85%

On the Potential Role of Trypsin and Trypsin Inhibitors in Acute Pancreatitis

1984
The protective role of alpha 2-macroglobulin, alpha 1-antitrypsin and Aprotinin against trypsin-induced effects on C3 and kininogen was studied in a human in vitro model. When human cationic trypsin was added to human serum or plasma, there was a gradual saturation of alpha 2-macroglobulin and later of alpha 1-antitrypsin.

Trypsinogen, Trypsin, Trypsin-Substrate and Trypsin-Inhibitor Complexes in Urea Solutions

European Journal of Biochemistry, 1968
The denaturation in urea of trypsinogen, trypsin and trypsin derivatives is first-order with respect to protein. 1 Structural modifications affecting the trypsinogen molecule were detected by studying the influence of pH on the rate of denaturation. The acidification of trypsinogen leads to the appearance of 2 reversible equilibria I′⇌ II′⇌ III′
