Origin: Photorhabdus
Properties: Pvc15 functions as tape measure protein and ATPase.

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).

Pvc15 is present at very low levels in the PVC syringes sample and is absent in CISs like phage T4 or R-type pyocins.According to previous studies,it possibly functions as tape measure protein and ATPase.
