Abstract

The described invention provides a method for detecting a target analyte that exhibits protease enzyme activity. The described method includes contacting a sample with a hybrid oxidase enzyme engineered to exhibit increased catalytic activity over that of a starting oxidase enzyme upon cleavage of a mutated protease cleavage recognition sequence. The mutated protease cleavage recognition sequence is a recognition sequence specific for the target analyte. The described method further includes contacting a substrate with the engineered hybrid oxidase enzyme. The substrate comprises a cognate composition of matter to the engineered hybrid oxidase enzyme, and the engineered hybrid oxidase enzyme is configured to catalyze conversion of the cognate composition of matter into a detectable product upon proteolytic cleavage of the mutated protease cleavage recognition sequence by the target analyte.
