Abstract

The present disclosure provides a method of producing enzyme-specific inhibitors or substrate binding partners comprising: identifying active site residues of the substrate in the enzyme substrate complex or in substrate binding partner-substrate complex; randomizing the active site residues to produce a combinatorial library of substrate variants; and selecting substrate variants that inhibit enzyme activity or bind substrate as substrate-specific binding partners. The present disclosure also provides ubiquitin enzyme specific inhibitors and ubiquitin variants that bind ubiquitin interaction motifs.
