Crystal structure of the Murray Valley encephalitis virus NS5 methyltransferase domain in complex with cap analogues. J.Gen.Virol., 88:2228-2236, 2007 Cited by PubMed Abstract: We have determined the high resolution crystal structure of the methyltransferase domain of the NS5 polypeptide from the Murray Valley encephalitis virus. This domain is unusual in having both the N7 and 2'-O methyltransferase activity required for Cap 1 synthesis. We have also determined structures for complexes of this domain with nucleotides and cap analogues providing information on cap binding, based on which we suggest a model of how the sequential methylation of the N7 and 2'-O groups of the cap may be coordinated.
