This protein blocks the end of the tube before DNA ejection while forming a channel perforating the host membrane in the process by adopting a hexameric tube structure with six flexible hydrophobic loops. This entry represents the region of the protein that forms the central part of the tube. It is organised into an alpha/beta subdomain, a long loop that protrudes from the inner wall covering about two-thirds of the tube, and a beta-domain in which the beta-strands are almost parallel with the tube axis [1].
