Protease cofactor
WebbMultiplexed Isobaric Tagging Reagents for Protein Expression Analysis List of Key Publications SCIEX iTRAQ® reagents were first launched at ASMS 2004 and quickly became adopted as a powerful mainstream proteomics technique. WebbJ Biol Chem. April 18, 2024. Tissue factor pathway inhibitor (TFPI), the main inhibitor of initiation of coagulation, exerts an important anticoagulant role through the factor Xa (FXa)-dependent inhibition of tissue factor/factor VIIa (FVIIa). Protein S is a TFPI cofactor, enhancing the efficiency of FXa inhibition.

WebbCofactor binding was strictly dependent on the glycerol content of buffer solutions and was not significantly influenced by substrate saturation of the enzyme. NS4A peptide binding to NS3 was accompanied by changes in the circular dichroism spectrum in the region between 270 and 290 nm, as well as by an enhancement of tryptophan fluorescence. Webb28 juni 2005 · We have discovered that introduction of appropriate amino acid derivatives at P'2 position improved the binding potency of P3-capped alpha-ketoamide inhibitors of HCV NS3 serine protease. X-ray crystal structure of one of the inhibitors (43) bound to the protease revealed the importance of the P'2 moiety ... Macromolecules

WebbHeparan sulfate is a glycosaminoglycan that enhances the activity of antithrombin, a serine protease inhibitor. 9 The pharmaceutical anticoagulant heparin, manufactured from porcine gut tissues, resembles EC heparan sulfate in its antithrombin activity. Webb7 aug. 2024 · α1-Antiproteinase (AAP), also known as α1-antitrypsin, is the main serine protease inhibitor of human plasma. Individuals with a point mutation in exon 5 of the AAP gene, which results in a single amino acid substitution in the protein, have diminished secretion of AAP from the liver.
WebbThe cofactor binding site of the serpin has never been mapped. Here we show that residues Lys284, Lys285 and Arg287 of C1-inhibitor play key roles in binding heparin and delivering the rate enhancement seen in the presence of polyanions and thus most likely represent the key cofactor binding residues for the serpin.
