Key result
Bioinformatics analysis identified 73 viral proteins across 29 viral species as highly probable metal-binding proteins, predominantly interacting with magnesium and zinc ions.
Why the study?
Metalloproteins and metal-based inhibitors effectively combat infectious diseases, particularly those caused by RNA viruses, but the identification and role of metal-binding proteins across human RNA viruses required comprehensive characterization.
Bioinformatics analysis identified 73 metal-binding proteins in human RNA viruses, highlighting the critical role of magnesium and zinc in viral processes like replication and host entry.

Metalloproteins and metal-based inhibitors have been shown to effectively combat infectious diseases, particularly those caused by RNA viruses. In this study, a diverse set of bioinformatics methods was employed to identify metal-binding proteins of human RNA viruses. Seventy-three viral proteins with a high probability of being metal-binding proteins were identified. These proteins included 40 zinc-, 47 magnesium- and 14 manganese-binding proteins belonging to 29 viral species and eight significant viral families, including Coronaviridae, Flaviviridae and Retroviridae. Further functional characterization has revealed that these proteins play a critical role in several viral processes, including viral replication, fusion and host viral entry. They fall under the essential categories of viral proteins, including polymerase and protease enzymes. Magnesium ion is abundantly predicted to interact with these viral enzymes, followed by zinc. In addition, this study also examined the evolutionary aspects of predicted viral metalloproteins, offering essential insights into the metal utilization patterns among different viral species. The analysis indicates that the metal utilization patterns are conserved within the functional classes of the proteins. In conclusion, the findings of this study provide significant knowledge on viral metalloproteins that can serve as a valuable foundation for future research in this area.
