This family represents the phage-tail-tube protein from a set of Siphoviridae from Gammaproteobacteria. Tail tube proteins polymerise with the assistance of the Tail-tip complex, a tape measure protein and two chaperones. Infectivity of host is delivered through the tube [1]. Members of this family from hexameric ring arrangement [2].	Domain
