pvc8

Profile

Name: PVC8
Base Pairs: 1617bp
Origin: Photorhabdus
Properties: PVC8 is a part of PVC Spike.

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).

Pvc8 is a fusion protein of T4 gp5 and gp27 homologs and is involved in the association between the wedges and the central hub. It is a part of the simplified architecture of T4 phage baseplate lying in the PVC syringe with pvc5, pvc7 and pvc10. Opposite surface charges are found on two sides of its hexameric rings .
