Pvc3 is a part of the sheath.

Profile

Name: Pvc3
Base Pairs: 1323 bp
Origin: Photorhabdus
Properties: Pvc3 is a part of the sheath.

Usage and Biology

Photorhabdus virulence cassette (PVC) is one group of extracellular Contractile injection systems (CISs) that are cell-puncturing nanodevices and present in both bacteria and archaea.[1]In structure, PVCs are macromolecular complexes containing a rigid tube structure housed in a contractile sheath, which is anchored to a baseplate and sharpened by a spike protein.[2](Figure 1)

Figure 1. Schematic of the PVCpnf locus. It contains 16 structural and accessory genes , followed by two payload genes (Pdp1 and Pnf, in red) and four putative regulatory genes (in pink).

Pvc3 consists of the sheath with Pvc2 and Pvc4. Pvc3 contains an extra protrusion domain, which is used for tailfiber docking, is in a comparable position of domain III in the T6SS sheath. A part of sheath, comprises alternating Pvc2 and Pvc3 subunits, which both interact with Pvc1. At the end of assembly, Pvc3 starts to assemble along the inner tube for the maturation of PVC particles with Pvc2.
