The paper by Pletnev ture flavivirion containing prM (about 170 residues) et al. The Evolution of Enveloped Viruses E2 projects upward to the full-length of the spike. Thus, The parallels between the assembly of alphaviruses and E1 forms what has been called the skirt that surrounds flaviviruses and the similarities in structure revealed by the lipid bilayer and part of the lower domains of the the present studies suggest that an enveloped virus spikes, whereas E2 forms the projecting part of the with an icosahedral structure arose long ago and has spike. viruses whose structures are more or less known use quite different assembly mechanisms ( Virus evolution	./cache/cord-267046-ewnjgps5.txt	./txt/cord-267046-ewnjgps5.txt
