cord-300884-rqfxe0x1	Zhang, Jianqiang	Genomic characterization of equine coronavirus	2007-12-05		.txt	text/plain	6804	378	56	Analysis of the sequence identified 11 open reading frames which encode two replicase polyproteins, five structural proteins (hemagglutinin esterase, spike, envelope, membrane, and nucleocapsid) and four accessory proteins (NS2, p4.7, p12.7, and I). In contrast to the replicase proteins which are directly translated from the genomic RNA, coronavirus structural and accessory proteins are expressed from a nested set of 3′ coterminal subgenomic (sg) mRNAs that also possess a common 5′ leader sequence derived from the 5′ end of the genome (Pasternak et al., 2006; Sawicki et al., 2007) . Following multiple alignments with the S proteins of other group 2a coronaviruses, a potential cleavage recognition sequence (RRQRR) was identified at residues 764-768 which would predict a cleavage between amino acids 768 and 769, separating the ECoV S protein into S1 and S2 subunits (Fig. 1) .	./cache/cord-300884-rqfxe0x1.txt	./txt/cord-300884-rqfxe0x1.txt
