Protein Domain : T6S-associated protein TagF superfamily IPR038225

Type	Homologous_superfamily
Description	This entry includes the T6S-associated protein, TagF, a post-translational repressor of the hemolysin co-regulated secretion island I (HSI-I)-encoded type VI secretion system (H1-T6SS), found in Pseudomonas aeruginosa. The type VI secretion system (T6SS) is found broadly among the Proteobacteria and is implicated in diverse processes including host-cell interactions, biofilm formation and gene regulation. Furthermore, studies indicate that the T6SS plays a critical role in interbacterial interactions. TagF has been shown to regulate the activity of the H1-T6SS in a manner that does not require phosphorylated-Fha1, PpkA, or other Tag proteins. TagF forms a homodimer with nearly identical monomers composed of alpha and beta elements assembled as a three-layer sandwich (α-β-alpha) [ ].
