The substrate-binding site of MERS-CoV PL pro features significant differences from those of the corresponding SARS-CoV enzyme and human ubiquitin-specific proteases (USPs, such as, USP14) (Hu et al., 2005; Chou et al., 2014; Ratia et al., 2014) . Hence, we crystallized the ubiquitin (Ub) complex of a MERS-CoV PL pro variant that had the active-site Cys111 replaced by serine (C111S) and determined the structure at 3.16 Å ( Figure 1A ). Crystal structure of the Middle East respiratory syndrome coronavirus (MERS-CoV) papain-like protease bound to ubiquitin facilitates targeted disruption of deubiquitinating activity to demonstrate its role in innate immune suppression ./cache/cord-329876-4cgrjnjo.txt ./txt/cord-329876-4cgrjnjo.txt
