The best studied is the soybean ( Glycine max ) trypsin inhibitor (STI), a representative member of the Kunitz-type Ser PIN family whose characterization has provided a basic understanding of the mechanism of …
WebChymotrypsins, such as Chymotrypsin C (also known as pancreatic Chymotrypsin or Chymotrypsin), are digestive enzymes that can perform proteolysis by cleaving peptides at the carboxyl side of tyrosine, tryptophan and phenylalanine, although over time they can also hydrolyze other amide bonds, especially those with leucine-donated carboxyls. WebWhen plant PIs bind to the digestive proteinases of insects, they block the digestion of proteins, leading to developmental delays and increased mortality. Pin I and II inhibitors target the digestive serine proteinases …
