10-221 4.40e-48

VirB8 protein; VirB8 is a bacterial virulence protein with cytoplasmic, transmembrane, and periplasmic regions. It is thought that it is a primary constituent of a DNA transporter. The periplasmic region interacts with VirB9, VirB10, and itself. This family also includes the conjugal transfer protein family TrbF, a family of proteins known to be involved in conjugal transfer. The TrbF protein is thought to compose part of the pilus required for transfer. This domain has a similar fold to the NTF2 protein.

periplasmic domain of VirB8 protein; This family contains the periplasmic domain of VirB8 protein which is an essential assembly factor of type IV secretion system (T4SS) channel proteins that are highly diverse in function relative to other bacterial secretion systems. T4SS proteins are important virulence factors for many Gram-negative pathogens, such as Agrobacterium, Brucella, Legionella, and Helicobacter. VirB8 is a bacterial virulence protein with cytoplasmic, transmembrane, and periplasmic regions. It is thought that VirB8 is a primary constituent of a DNA transporter. It is a crucial structural and functional component of the T4SS, with interactions between VirB8 and many other T4SS proteins, including VirB10, VirB9, VirB1, VirB4, and VirB11, as well as with itself.
