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 ...

Chitosan nanoparticles conjugate with trypsin and trypsin inhibitor
Carbohydrate Polymers, 2016Chitosan-protein conjugates are widely used in therapeutic drug delivery. We report the bindings of chitosan nanoparticles with trypsin (try) and trypsin inhibitor (tryi), using thermodynamic analysis and multiple spectroscopic methods. Thermodynamic parameters ΔS, ΔH and ΔG showed chitosan-protein bindings occur mainly via H-bonding and van der Waals ...

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 ...

SFTI-1 is a bicyclic 14 amino acid peptide that was originally isolated from the seeds of the sunflower Helianthus annuus. It is a potent inhibitor of trypsin, with a sub-nanomolar K(i) value and is homologous to the active site region of the well-known family of serine protease inhibitors known as the Bowman-Birk trypsin inhibitors.

Abstract Trypsin inhibitors were found in several food plants. Potato and sweet corn were the most inhibitory, while fruits had negligible activity. Intermediate in activity were sweet potato, spinach, broccoli, Brussels sprouts and cucumber. The trypsin inhibitor of sweet corn was isolated by extraction in dilute salt solution, ammonium sulfate ...

AbstractThe optical rotatory properties, amino acid composition, chromatographic fractionation, and enzymic inhibition activity of several trypsin inhibitors were investigated. The homogeneity of these proteins was tested by free boundary electrophoresis and sedimentation in the ultracentrifuge.

AbstractFor expressing trypsin inhibitor activity (TIA), trypsin units inhibited (TUI), trypsin inhibited, and trypsin inhibitors have been used. Although the last two units are preferred, their calculations in current practices require refinement.

Trypsin inhibitors for the treatment of pancreatitis
Bioorganic & Medicinal Chemistry Letters, 2016Proline-based trypsin inhibitors occupying the S1-S2-S1' region were identified by an HTS screening campaign. It was discovered that truncation of the P1' moiety and appropriate extension into the S4 region led to highly potent trypsin inhibitors with excellent selectivity against related serine proteases and a favorable hERG profile.

Coevolution of insect trypsins and inhibitors
Archives of Insect Biochemistry and Physiology, 2004AbstractMany plant proteinase inhibitors have lysine at the P1 position, presumably to avoid hydrolysis by insect trypsins. Lepidopteran trypsins appear to have adapted to resist proteinase inhibitors through increased inhibitor hydrolysis and decreased binding to inhibitor hydrophilic reactive sites.
