(1) the genetic study of pancreatic proteinase in mice(2) Researchers isolated the protein, a cysteine proteinase , from cultured tissue of resistant corn plants and obtained a patent last November for the gene sequence that encodes it.(3) This site is well characterized in trypsin and other serine proteinases .(4) Such hydrolytic enzymes as cystein proteinases, serine proteinases , and nucleases are highly induced during xylogenesis.(5) The morphological and biochemical changes typical of apoptosis are orchestrated by caspases, a family of cysteine proteinases , which cleave proteins after aspartate residue.(6) The inhibition of proteinases by protein proteinase inhibitors is an individual case of protein-protein interaction.
