WebNov 22, 2024 · Hcp (haemolysin-coregulated protein) is an effector protein in the type-VI secretion system (T6SS), which is secreted by T6SS and functions as its structural component. The results of our previous genomic sequencing showed that hcp existed in the mesophilic A. salmonicida SRW-OG1 isolated from naturally infected Epinephelus coioides. WebThe T6SS is thought to resemble an inverted phage extending outward from the bacterial cell surface. It consists of 14 proteins that assemble into three sub-complexes: a phage tail …
CDD Conserved Protein Domain Family: T6SS_HCP
WebOct 19, 2024 · Typically, the T6SS gene cluster encodes at least 13 conserved core components for the apparatus assembly and other less conserved accessory proteins and effectors. It functions as a contractile tail machine comprising a TssB/C sheath and an expelled puncturing device consisting of an Hcp tube topped by a spike complex of VgrG … WebOct 5, 2015 · Overall, these observations suggested that T6SS could function as an inverted phage tail and use the contraction of a sheath-like structure to drive the Hcp tube with associated VgrG-effector spike out of the cells [ 19, 24, 25 ]. The first idea about overall structure and mode of action of T6SS came from a study of T6SS in V. cholerae [ 26 ]. tri state oxygen ashland ky
Sensing of intracellular Hcp levels controls T6SS …
WebFeb 18, 2009 · Moreover, two T6SS-secreted proteins were previously identified, namely the members of the Hcp and VgrG families. A T6SS working model could be the recognition of the Hcp and VgrG substrates by ClpV, threading through the oligomeric ClpV central channel, unfolding of the substrates while they move across the ClpV pore and possibly towards … WebOct 9, 2024 · Surprisingly, the T6SS inner tube protein Hcp is accumulated intracellularly even in nutrient-poor media, when the T6SS is not assembled. We found that Hcp interacts with the transcription factor Clp required for activating … WebJun 8, 2024 · In regard to its mechanism of action, the T6SS is sometimes compared to a crossbow or speargun in that contractile sheath proteins Clp V -interacting protein A and B (VipA-VipB) cover a nanotube of stacked hexamers (hemolysin-coregulated proteins [Hcp]) that make up the body of the arrow [ 10 ]. tri state pain bullhead
