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.
