FIG. 3.

Comparison of the deduced amino acid sequences encoded by EIAV_UK with the 19-2 sequence, the EIAV_PV consensus sequence, and the sequence of a cloned representative of the EIAV_PR strain. Comparisons shown are for ORF S2 (A), ORF S3, which encodes the second exon of rev (B), and the envelope glycoprotein (C). Only the amino acid residues that differ from the total consensus sequence are indicated. A dash indicates that no consensus sequence was found. Potential N-linked glycosylation sites are underlined. Potential N-linked glycosylation sites that differ between (EIAV_UK and EIAV_PV) and EIAV_PR and 19-2) are marked by asterisks.
