West Nile Virus Methyltransferase Catalyzes Two Methylations of the Viral RNA Cap through a Substrate-Repositioning Mechanism

Flaviviruses encode a single methyltransferase domain that sequentially catalyzes two methylations of the viral RNA cap, GpppA-RNA→m(7)GpppA-RNA→m(7)GpppAm-RNA, by using S-adenosyl-l-methionine (SAM) as a methyl donor. Crystal structures of flavivirus methyltransferases exhibit distinct binding site...
