cord-289965-qcezqpze	Lehmann, Kathleen C.	Arterivirus nsp12 versus the coronavirus nsp16 2′-O-methyltransferase: comparison of the C-terminal cleavage products of two nidovirus pp1ab polyproteins	2015-09-01		.txt	text/plain	6580	356	50	The 39-terminal domain of the most conserved ORF1b in three of the four families of the order Nidovirales (except for the family Arteriviridae) encodes a (putative) 29-O-methyltransferase (29-O-MTase), known as non structural protein (nsp) 16 in the family Coronaviridae and implicated in methylation of the 59 cap structure of nidoviral mRNAs. As with coronavirus transcripts, arterivirus mRNAs are assumed to possess a 59 cap although no candidate MTases have been identified thus far.
