Targeting Viral Methyltransferases: An Approach to Antiviral Treatment for ssRNA Viruses.

ABSTRACT: Methyltransferase enzymes have been associated with different processes within cells and viruses. Specifically, within viruses, methyltransferases are used to form the 5'cap-0 structure for optimal evasion of the host innate immune system. In this paper, we seek to discuss the various methyltransferases that exist within single-stranded RNA (ssRNA) viruses along with their respective inhibitors. Additionally, the importance of motifs such as the KDKE tetrad and glycine-rich motif in the catalytic activity of methyltransferases is discussed.
