Figure 5.

Amino Acid – alignment of the GH-loop (residues 140–160) from both serotype A lineages IRN99 and IRN96. Virus isolates are named after the Genbank Accession-number. Complete deletion at site 153 of the IRN99 lineage, as well as lineage specific conserved amino acids at the sites: 144, 166, 183, 202 and 203. The potential integrin binding site Arg-Gly-Asp (RGD) [8], is in all but DQ296541, as 'RGDLGAL'-motif present.
