VirB10 forms part of core complex in Type IV secretion system (T4SS); This family contains VirB10, a component of the type IV secretion system (T4SS), including homologs TrbI, TraF, TrwE and TraL. T4S system is employed by pathogenic bacteria to export virulence DNAs and/or proteins directly from the bacterial cytoplasm into the host cell. It forms a large multiprotein complex consisting of 12 proteins termed VirB1-11 and VirD4. VirB10, interacts with VirB7 and VirB9, forming the membrane-spanning 'core complex' (CC), around which all other components assemble. The CC is inserted in both, the outer and inner membranes, playing a fundamental role as a scaffold for the rest of the T4SS components and actively participating in T4S substrate transfer through the bacterial envelope via conformational changes regulating channel opening and closing. TrwE in R33 plasmid has been shown to be anchored to the inner membrane and its C-terminal is necessary for conjugation; the transmembrane domains of TrwB and TrwE are involved in TrwB-TrwE interactions. TraF protein of the RP4 plasmid is involved in circularization of pilin subunits of P-type pili. In gonococcal genetic island (GGI) of Neisseria gonorrhoeae, T4SS encodes TrbI and circularization occurs via a covalent intermediate between the C terminus of putative pilin protein TraA and TrbI.

membrane protein insertase, YidC/Oxa1 family, N-terminal domain; Essentially all bacteria have a member of the YidC family, whose C-terminal domain is modeled by TIGR03592. The two copies are found in endospore-forming bacteria such as Bacillus subtilis appear redundant during vegetative growth, although the member designated spoIIIJ (stage III sporulation protein J) has a distinct role in spore formation. YidC, its mitochondrial homolog Oxa1, and its chloroplast homolog direct insertion into the bacterial/organellar inner (or only) membrane. This model describes an N-terminal sequence region, including a large periplasmic domain lacking in YidC members from Gram-positive species. The multifunctional YidC protein acts both with and independently of the Sec system. [Protein fate, Protein and peptide secretion and trafficking]

VirB10 and similar proteins form part of core complex in Type IV secretion system (T4SS); This family contains VirB10, a component of the type IV secretion system (T4SS) and its homologs, including TraB, TraF, IcmE, and similar proteins. T4S system is employed by pathogenic bacteria to export virulence DNAs and/or proteins directly from the bacterial cytoplasm into the host cell. It forms a large multiprotein complex consisting of 12 proteins termed VirB1-11 and VirD4.

In Gram-negative bacterial pathogen Helicobacter pylori, an important aetiological agent of gastroduodenal disease in humans, the comB3 gene encodes protein with best homologies to TraS/TraB from the Pseudomonas aeruginosa conjugative plasmid RP1 and TrbI of plasmid RP4 and VirB10 from the Ti plasmid of Agrobacterium tumefaciens, as well as DotG/IcmE of Legionella pneumophila.

DotG/IcmE is a homolog of VirB10 which forms part of core complex in Type IV secretion system; This family contains DotG/IcmE (VirB10 homolog) and a component of the type IV secretion system (T4SS), and similar proteins. The Dot/Icm system is a T4SS found in the pathogens Legionella and Coxiella and the conjugative apparatus of IncI plasmids; T4SS is employed by pathogenic bacteria to export virulence DNAs and/or proteins directly from the bacterial cytoplasm into the host cell. Similar to T4SS VirB/D components, the Legionella Dot/Icm secretion apparatus contains a critical five-protein sub-assembly that forms the membrane-spanning 'core-complex' (CC), around which all other components assemble. This transmembrane connection is mediated by protein dimer pairs consisting of two inner membrane proteins, DotF and DotG, each independently associating with DotH/DotC/DotD in the outer membrane.
