We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

As the COVID-19 pathogen, SARS-CoV-2 relies on its main protease (M(Pro)) for pathogenesis and replication. During crystallographic analyses of M(Pro) crystals that were exposed to the air, a uniquely Y-shaped, S-O-N-O-S-bridged post-translational cross-link that connects three residues C22, C44, and K61 at their side chains was frequently observed. As a novel covalent modification, this cross-link serves potentially as a redox switch to regulate the catalytic activity of M(Pro), a demonstrated drug target of COVID-19. The formation of this linkage leads to a much more open active site that can potentially be targeted for the development of novel SARS-CoV-2 antivirals. The structural rearrangement of M(Pro) by this cross-link indicates that small molecules that lock M(Pro) in the cross-linked form can potentially be used with other active-site-targeting molecules such as paxlovid for synergistic effects in inhibiting SARS-CoV-2 viral replication. | As the COVID-19 pathogen, SARS-CoV-2 relies on its main protease (M(Pro)) for pathogenesis and replication.
