Five Rotational Registers Define Modular Portal-Capsid Assembly in Cyanophage P-SSP7
The virus P-SSP7 infects the cyanobacterium Prochlorococcus marinus, one of the most abundant photosynthetic microbes in the ocean, making this pairing a useful model for studying host-virus interactions. Infection proceeds through a portal-tail complex that attaches to the viral protein shell at a single specialized v...
