Fowl trypsin and chymotrypsin
By chromatography on a carboxymethylcellulose column, trypsin and chymotrypsin have been obtained from fowl pancreatic gland. The molecular weights, isoelectric points, and optimum reactions of the media for activity and heat stability have been determined, and the behavior of these enzymes with respect to natural trypsin inhibitors has been investigated. A comparative study of the enzymes of the fowl and of large horned cattle has been performed.
