+== Publication Abstract from PubMed ==
+Sequence-nonspecific binding of RNA, recognition of a 7-methylguanosine 5' mRNA cap, and methylation of a nucleic acid backbone are three crucial and ubiquitous events in eukaryotic nucleic acid processing and function. These three events occur concurrently in the modification of vaccinia transcripts by the methyltransferase VP39. We report the crystal structure of a ternary complex comprising VP39, coenzyme product S-adenosylhomocysteine, and a 5' m7 G-capped, single-stranded RNA hexamer. This structure reveals a novel and general mechanism for sequence-non-specific recognition of the mRNA transcript in which the protein interacts solely with the sugar-phosphate backbone of a short, single-stranded RNA helix. This report represents the first direct and detailed view of a protein complexed with single-stranded RNA or 5'-capped mRNA.
