This entry represents domain I from bacteriophage tail sheath proteins such as Gp18, a protein that surrounds the central non-contractile tail tube of the tail sheath from bacteriophages, which contracts during infection [1,2]. These proteins consist of three domains, domains I, II (Pfam:PF17481) and III (Pfam:PF17482). Domains I and II form the protease-resistant fragment [1].	Domain
