1933Kunitz & Northrop in Science LXXVIII. 558/1 This note describes the isolation from fresh pancreas of an active crystalline protein which is converted by minute amounts of trypsin into a powerful proteolytic enzyme... The inactive protein has been called chymo-trypsinogen and the active protein chymo-trypsin. 1956Nature 10 Mar. 472/1 The viscosity of chymotrypsin increases sharply as a function of urea concentration. Ibid. 17 Mar. 527/2 Chymotrypsin digestion gave three products which were separated by paper electrophoresis. 1964G. H. Haggis et al. Introd. Molec. Biol. iv. 98 The peptic enzymes pepsin, trypsin and chymotrypsin are formed from pepsinogen, trypsinogen and chymotrypsinogen. 1967New Scientist 17 Aug. 333/1 Chymotrypsin is..a protein-digesting enzyme, itself solely composed of protein (in the form of three ‘strings’ of linked amino acids) and found in the pancreas of man and other animals. |
