the enzyme exhibited hydrolytic activity with several proteins and esterolytic activity with many synthetic substrates , including benzoylarginine ethyl ester and acetyltyrosine ethyl ester.a comparison of the properties of the enzyme with those of known yeast proteinases led to the conclusion that the chitin synthestase activating factor is identical with the enzyme previously designated as proteinase b ( ec 3.4.22.9 ) .
