Mutations at the apeA locus in Salmonella typhimurium lead to loss of a soluble enzyme ("protease I") that hydrolyzes the chromogenic endoprotease substrate N-acetyl phenylalanine beta-naphthyl ester. We have isolated pseudorevertants of S. typhimurium apeA mutations that have regained the

The results of this study demonstrated that proteolytic enzymes in pancreatic juice from pigs prepared with the pouch method (PM) were nearly fully active or were fully active. When activation with enterokinase was carried out further inactivation and/or breakdown occurred

Two cytochemical methods for detection of granulocytic elastase and chymotrypsin employing alanine and phenylalanine naphthyl esters were developed. Specificity of reaction with the ester substrates was proven by chloromethyl ketone inhibitors. The results of both staining methods were almost identical

A cationic Schistosoma mansoni cercarial antigen was shown to be a serine protease as it was capable of hydrolysing N-acetyl-DL-phenylalanine beta-naphthyl ester (NAPBNE) after precipitation by immunoelectrophoresis, and this reaction was modulated by the serine protease inhibitors phenylmethanesulfonyl fluoride (PMSF)

A technique for quickly detecting nanogram quantities of low- and high-molecular-weight inhibitors of some serine proteases is described. The inhibitor solutions are spotted onto agar films which contain either L-1-p-tosylamino-2-phenylethyl chloromethyl ketone (TPCK)-trypsin or tosyl lysine chloromethyl ketone (TLCK)-chymotrypsin.
