Methods for identifying modified proteases with modified substrate specificity or other properties are provided. The methods screen candidate and modified proteases by contacting them with a substrate, such as a serpin, an alpha macroglobulins or a p35 family protein or modified serpins and modified p35 family members or modified alpha macroglobulins, that, upon cleavage of the substrate, traps the protease by forming a stable complex. Also provided are modified proteases. |
