The hydrogen-ion equilibria of α-chymotrypsin, monoacetyl-α-chymotrypsin and diisopropylphosphoryl-α-chymotrypsin

Biochimica et Biophysica Acta (BBA) - Specialized Section on Enzymological Subjects, 1964
Abstract Based on the titration curves, the hydrogen-ion equilibria of α-chymotrypsin (EC 3.4.4.5), monoacetyl-α-chymotrypsin and diisopropylphosphoryl-α-chymotrypsin are identical within experimental error. This finding rules out various mechanisms which require the masking or the release of an ionizing residue for catalytic activity.

Stability of Alpha-Chymotrypsin

Archives of Ophthalmology, 1961
Following the early reports by Barraquer 1 and Jenkins 2 on the use of α-chymotrypsin in cataract surgery, ophthalmic surgeons have shown considerable interest in the further development of this new technique. This communication details results that indicate by both biochemical assay and clinical experience, at least one commercial α-chymotrypsin ...

Peptide aldehydes inhibiting chymotrypsin

Biochemical and Biophysical Research Communications, 1972
Abstract Peptide aldehydes, in which the argininal moiety of leupeptin Ac (Ac-Leu-Leu-argininal) was replaced by phenylalaninal, tyrosinal or tryptophanal, were synthesized. These compounds exhibited potent inhibition on the proteolytic activity of chymotrypsin in contrast with leupeptin which was reported to inhibit trypsin.

ANAPHYLACTIC REACTION TO CHYMOTRYPSIN

Journal of the American Medical Association, 1960
Proteolytic enzyme therapy has been employed in various diseases in which its anti-inflammatory and fibrinolytic effects have been of value. Among such agents, aqueous chymotrypsin (Chymar) has been described as relatively free of undesirable side-effects.

Adhesive Otitis and Chymotrypsin

Acta Oto-Laryngologica, 1964
The chemistry, biochemistry and previous clinical experiences with chymotrypsin is briefly mentioned. This preliminary report states the principles of treatment and early results in a number of patients with chronic secretory otitis media.

Sedimentation equilibrium studies of human chymotrypsin II and bovine δ-chymotrypsin

Archives of Biochemistry and Biophysics, 1973
Abstract Sedimentation equilibrium experiments indicate that neither human chymotrypsin II nor bovine δ-chymotrypsin molecules undergo association in the pH range 3–5 where dimerization occurs with α-chymotrypsin. The weight-average molecular weights of human chymotrypsin II and δ-chymotrypsin in a pH 4.4 0.1 ionic strength buffer are 26,200 and 26 ...

Acetaldehyde inhibits chymotrypsin and serum anti-chymotrypsin activity.

Journal of investigative medicine : the official publication of the American Federation for Clinical Research, 1998
Chymotrypsin (CT) and CT-like enzymes contribute to the dynamics of metabolism by their participation in digestion, peptide hormone generation and catabolism, fertilization of ova and inhibition of thrombin-induced platelet aggregation, among other processes.
