UniProtKB description: Cell-perforating component and plug protein of the phage tail machine. Together with the internal ejection proteins is required for stabilization of the condensed DNA within the capsid by plugging the hole through which the DNA enters. Host cell membrane perforation allows viral DNA ejection. The needle penetrates the host outer membrane. The needle is released and the internal head protein gp7 is ejected to form an extra-cellular channel.
