the 55- ( h-uk ) and 36-kda forms ( l-uk ) of human urinary urokinase lost most of esterase activity toward acetyl-glycyl-l-lysine methyl ester upon reductive cleavage of 3 ss bonds with dithiothreitol in the presence of the competitive inhibitor , n alpha-benzoyl-l-arginine amide ( baa ) , bound to polyacrylyl azide with c16n3-arm ( paa ) at 0.3 m guanidine , a threshold point of the native state where a protein-denaturating transition began .
