Baseplate structural protein gp6 is located next to the tail tube and is an intermediate (or inner) baseplate protein involved in tail assembly. Two molecules of gp6 form a complex with gp25 and gp7 which is involved sheath contraction [1-3]. This domain has been described as C-terminal domain I, and adopts a 2-layer beta-sandwich fold.

A, B	PF21472	Baseplate structural protein gp6, C-terminal domain II (gp6_C-domII)	Baseplate structural protein gp6, C-terminal domain II	This entry represents domain II found in the C-terminal of gp6 from bacteriophage T4, which adopts a beta-barrel fold. This protein is involved in tail assembly. It forms the gp25-(gp6)2-gp7 module, involved in sheath contraction [1,2].	Domain
