Abstract

Viruses are highly robust protein-nucleic acid complexes that resist environmental insult, but are dynamic enough to efficiently deliver the viral chromosome upon interaction with a target host cell. Using cryo- electron microscopy and single particle analysis, we have been studying the complexes involved in DNA packaging in the Bacillus subtilis bacteriophage SPP1. Here we propose to determine structure of the bacteriophage tail-connector and tail-spike complexes that are involved in DNA translocation during infection of the host cell. The structures determined will allow us to analyse conformational changes during self-assembly by comparison with other states and by fitting the atomic structures of known components in the EM density maps.
