Chymotrypsin inhibitor mechanism
WebThe cycloamylose pathway of binding, acylation, and deacylation is formally similar to the pathway of chymotrypsin-catalyzed hydrolysis of esters. Comparisons of chymotrypsin catalyses and cycloamylose reactions are made, including a comparison of the second-order rate constants of these substances with substrates. 展开 WebThe chymotrypsin inhibitor activity is defined as the number of chymotrypsin units inhibited (CUI), and the results can be expressed as CUI per milligram of protein or per …

The hypoxic environment, induced by ischemia, is a potent stimulus for hypoxia inducible factor 1α (HIF-1α) upregulation and activation, which induce pro-angiogenic gene expression. We previously showed that the tyrosine phosphatase …
WebIn a previous successful attempt to convert trypsin to a chymotrypsin-like protease, 15 residues of trypsin were replaced with the corresponding ones in chymotrypsin. This suggests a complex mechanism of substrate recognition instead of a relatively simple one that only involves three sites, residues 189, 216 and 226.
