English: fig6: Models of the glycosylated alphavirus surface as derived from rodent(A) and mosquito (B) cells. The crystal structure of the CHKV E1–E2envelope glycoprotein complex was fitted into the Sindbis virus cryo-EMmap (PDB accession number 2XFB).12 E1 and E2 are shownin a surface representation in dark gray and light gray, respectively.Oligomannose-type glycans, presented by E2 at Asn200 and Asn262, areshown as light- and dark-green spheres, respectively (Man9GlcNAc2, from PDB accession code 2WAH(75)). At Asn141, glycan structures aremodeled as complex-type glycans for rodent-derived alphavirus (panelA; pink spheres, from PDB accession code 4BYH(74)) and paucimannose-typefor mosquito-derived alphavirus (panel B; orange spheres, from PDBaccession code 2WAH).
