We have determined the three-dimensional structures of the
wild-type Sindbis virus and two of its mutants that retain the E3
sequence within PE2. Using difference imaging between these mutants and
the wild-type virus, we have assigned a location for the 64-amino-acid
sequence corresponding to E3 in the mutant spike complex. In the
wild-type virus, the spike is composed of an E1-E2 heterotrimer. The E3
protein was found to protrude midway between the center of the spike
complex and the tips. Based on these results and the work of others, we
propose a distribution for the functional domains of the spike proteins
within the structure of wild-type Sindbis virus. Within the structure
of the virus, the E1 domains form the central portion of the spike
complex, while the tips are formed by the E2 domains that flare out
from the center of the complex. The structural similarity between these
Sindbis virus mutants and Ross River virus suggests that E3 may also be
present in the latter, which is also a member of the
Alphavirus genus.
