Abstract
Porcine epidemic diarrhea virus (PEDV) is a coronavirus that infects pigs and can have mortality rates approaching 100% in piglets, causing serious economic impact. The 3C-like protease (3CLpro) is essential for the coronaviral life cycle and is an appealing target for the development of therapeutics. We report the expression, purification, crystallization and 2.10 Å X-ray structure of 3CLpro from PEDV. Analysis of the PEDV 3CLpro structure and comparison to other coronaviral 3CLpro’s from the same alpha-coronavirus phylogeny shows that the overall structures and active site architectures across 3CLpro’s are conserved, with the exception of a loop that comprises the protease S2 pocket. We found a known inhibitor of severe acute respiratory syndrome coronavirus (SARS-CoV) 3CLpro, (
