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]
 
The PVC tube linked with payloads consists of three structurally similar tube proteins, such that a complete syringe in a typical length contains 24 stacked hexameric rings of tube proteins, including 2 layers of tube initiators and 22 layers of main tube proteins. Among all related genes,pvc5 produces pvc5 hexameric rings which stacks onto the Pvc7 ring to form the first two initiator rings in the baseplate end of the PVC tube through opposite surface charges and electrostatic attraction.Furthermore, pvc5 is encircled to form the first layer of the sheath which aims to prepare for the contraction in the delivery process.
