11. Blow later applied X-ray crystallography to study chymotrypsin , a digestive enzyme. 12. However, close relatives of chymotrypsin -like serine proteases are absent in plants. 13. It inhibits proteases like chymotrypsin , kallikrein, plasmin, thrombin, and trypsin. 14. This is done by the addition of proteolytic enzymes such as trypsin and chymotrypsin . 15. The pancreas secretes the precursors of a number of proteases such as trypsin and chymotrypsin . 16. Chymotrypsinogen ( the precursor of Chymotrypsin ). 17. PSMB5 is part of the 20S proteasome complex and has enzymatic activity similar to chymotrypsin . 18. It does not act on thrombin, trypsin or chymotrypsin and does not express fibrinolytic activity. 19. Chymotrypsin is synthesized in the pancreas by protein biosynthesis as a polypeptide molecule interconnected via disulfide bonds.20. The S1 pocket of chymotrypsin -like enzymes is more hydrophobic than in trypsin-like proteases.
