Conformational changes in and translocation of small proteins: insights into the ejection mechanism of podophages

Abstract excerpt

Podophage tails are too short to span the cell envelope during infection. Consequently, podophages initially eject the core proteins within the head for the formation of an elongated trans-envelope channel for DNA ejection. Although the core proteins of bacteriophage T7 have been resolved at near-atomic resolution, the mechanisms of core proteins and DNA ejection remain to be fully elucidated. In this study, we...
