Protein Domain : Type VI secretion system TssK IPR010263

Type  Family
Description  TssK is an essential baseplate component of the type VI secretion system, which connects the membrane complex, the baseplate and the tail components [ , , ].The structure of TssK was solved revealing the proteins organise into a tightly packed trimer [ , ]. Each TssK monomer comprises three domains: an N-terminal β-sandwich domain, a linker and a four-helix-bundle middle domain, and a C-terminal domain. The N-terminal domain of TssK is structurally homologous to the shoulder domain of phage receptor-binding proteins, and the C-terminal domain binds the T6SS membrane complex [].This family includes TssK proteins and TssK homologues ImpJ and vasE.The type VI secretion system (T6SS) is a supra-molecular bacterial complex that resembles phage tails. It is a toxin delivery systems which fires toxins into target cells upon contraction of its TssBC sheath [ ]. Thirteen essential core proteins are conserved in all T6SSs: the membrane associated complex TssJ-TssL-TssM, the baseplate proteins TssE, TssF, TssG, and TssK, the bacteriophage-related puncturing complex composed of the tube (Hcp), the tip/puncturing device VgrG, and the contractile sheath structure (TssB and TssC). Finally, the starfish-shaped dodecameric protein, TssA, limits contractile sheath polymerization at its distal part when TagA captures TssA [].
