The ϕPA3 phage nucleus is enclosed by a self-assembling 2D crystalline lattice
Abstract
To protect from host attack, numerous jumbo bacteriophages establish a micron-scale, protein-based structure to enclose their replicating DNA. Using cryoEM, the authors show that the 2D crystal enclosing this so-called phage nucleus is an assembly of tetramers linked by flexible loops and tails.
