2.1.1.56	additional information	enzyme sequentially methylates the guanine N-7 and ribose 2'-O positions of viral RNA cap. The order of two methylations is determined by the preference of 2'-O methylation for substrate m7GpppA-RNA to GpppA-RNA, and the 2'-O methylation is not absolutely dependent on the prior N-7 methylation	Dengue virus	?	-	?	89
