Mass spectrometric assays monitoring the deubiquitinase activity of the SARS-CoV-2 papain-like protease inform on the basis of substrate selectivity and have utility for substrate identification
Description
The SARS-CoV-2 papain-like protease (PL^(pro)) and main protease (M^(pro)) are nucleophilic cysteine enzymes that catalyze hydrolysis of the viral polyproteins pp1a/1ab. By contrast with M^(pro), PL^(pro) is also a deubiquitinase (DUB) that accepts
