Method for detecting protein inhibitors and ligands of medical value

摘要

The invention relates to a method for detecting inhibitors or ligands of binding domains, which comprises using a protein which contains at least one catalytic domain and at least one binding domain, incubating said protein with a marker substrate which binds to the catalytic domain of the protein and is converted, with a substrate which can reversibly bind to the catalytic domain and to the binding domain, and with the inhibitor and determining whether the marker substrate is converted by the protein.
