Substrates and methods for assaying deubiquitinating enzymes activity

摘要

The invention relates to substrates and methods suitable for assaying deubiquitinating enzyme activity, and in particular for screening inhibitors of enzymes involved in removal of mono or poly-ubiquitin chains from a target protein as well as inhibitors of ubiquitin precursors. Such inhibitors may have utility in the treatment of disease states associated with ubiquitin processing as well as proteolysis.
