Tumour-associated trypsin inhibitor and tumour-associated trypsin
Scandinavian Journal of Clinical and Laboratory Investigation, 1990Tumour-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%

Archives of Biochemistry and Biophysics, 1974
Abstract Fetuin per se is a moderately strong trypsin inhibitor of the temporary type and retains its antitryptic activity upon desialicization. It forms a reversible 1:1 complex with β-trypsin and is functionally homogeneous in this respect. Complex formation is an entropy-driven reaction evidently due to release of structured water associated ...

Interactions between trypsin, α2 macroglobulin and soybean trypsin inhibitor
Biochemical and Biophysical Research Communications, 1973Abstract The present study reveals that a trypsin- α 2 macroglobulin complex cannot be dissociated by the intervention of soybean trypsin inhibitor even after a 60 hour-incubation time. If the inhibitor is first bound to trypsin, the addition of α 2 macroglobulin restores about 60% of the enzyme activity.

Trypsinogen, Trypsin, Trypsin-Substrate and Trypsin-Inhibitor Complexes in Urea Solutions
European Journal of Biochemistry, 1968The 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′

TRYPSIN AND TRYPSIN INHIBITORS FROM PENAEID SHRIMP
Journal of Food Biochemistry, 2002Trypsin 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.

Energy embedding of trypsin inhibitor
Biopolymers, 1982AbstractEnergy 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 ...

Heat of reaction between trypsin and soybean trypsin inhibitor
Archives of Biochemistry and Biophysics, 1952Abstract 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.

Aggregation of trypsin and trypsin inhibitor by Al cation
Journal of Photochemistry and Photobiology B: Biology, 2017Al cation may trigger protein structural changes such as aggregation and fibrillation, causing neurodegenerative diseases. We report the effect of Al cation on the solution structures of trypsin (try) and trypsin inhibitor (tryi), using thermodynamic analysis, UV-Visible, Fourier transform infrared (FTIR) spectroscopic methods and atomic force ...

Interaction of Urinary Trypsin Inhibitor, UTI68, with Bovine Trypsin
The Journal of Biochemistry, 1982One 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 ...
