Protein Domain : Type VI secretion system TssN IPR035177

Type	Family
Description	TssN proteins have multiple predicted transmembrane (TM) regions. In Flavobacterium johnsoniae, three specific components (TssN, TssO and TssP) are absent in the other sub-types of T6SS [ ].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 [].
