This entry includes the phage lambda head-tail attachment protein FII that is required for the joining of phage heads and tails at the last step of morphogenesis [1]. Plays a role in virion assembly by joining the head and the tail at the last step of morphogenesis. Six FII proteins probably bind protein W that closes the DNA-filled capsid, as well as the U tail terminator protein of the pre-assembled tail.	Domain
