Profile

Name: pvc9
Base Pairs: 423 bp
Origin: Photorhabdus
Properties: Pvc9 is a part of pvc baseplate.

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).

The residues 10–60 of Pvc9 highlight a siginificant role in organizing the core bundle of wedge proteins.
Encircling Pvc7,it acts as a sheath initiator.
