Usage and Biology

Photorhabdus virulence cassette (PVC) is one group of extracellular Contractile injection systems (CISs) that are cell-puncturing nanodevices for targeted delivery of proteins .[1]Structurally similar to other CISs, PVCs are also 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](Figure1)

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).

In the assembled wedges, six copies of Pvc11-Pvc12 heterodimers form a hexagonal ring through the dimerization between the domain V of pvc11 and the domain III of pvc12 from a neighboring heterodimer.
Using an extrusion for the interactions with adjacent domains with pvc11.
One part involved in the association between the wedges and the central hub.
