Metal-binding proteins and proteases in RNA viruses: unravelling functional diversity and expanding therapeutic horizons.

Metal-binding proteins are pivotal components with diverse functions in organisms, including viruses. Despite their significance, many metalloproteins in viruses remain uncharacterized, posing challenges to understanding viral systems. This study addresses this knowledge gap by identifying and analyzing metal-binding proteins and proteases in RNA viruses. The findings emphasize the prevalence of these proteins as essential functional classes within viruses and shed light on the role of metal ions and metalloproteins in viral replication and pathogenesis. Moreover, this research serves as a crucial foundation for further investigations in this field, offering the potential for developing innovative antiviral strategies. Additionally, the study enhances our understanding of the distribution and evolutionary patterns of metal-binding proteases in major human viruses. Continually exploring metal-binding proteomes across diverse viruses will deepen our knowledge of metal-dependent biological processes and provide valuable insights for combating viral infections, including respiratory viruses and other life-threatening diseases.
