Bacteriophage P22 Capsid as a Pluripotent Nanotechnology Tool

Area of Science:

• Biotechnology
• Nanotechnology
• Structural Biology

Background:

• The Salmonella enterica bacteriophage P22 is an icosahedral T=7 capsid.
• It is composed of coat protein (gp5) and scaffold protein (gp8).
• P22 capsids exhibit structural plasticity, forming three distinct morphologies.

Purpose of the Study:

• To review the literature on the bacteriophage P22.
• To highlight its potential as a virus-like particle (VLP) nanocage.
• To explore its applications in nanoplatform design.

Main Methods:

• Review of existing scientific literature on bacteriophage P22.
• Analysis of P22 capsid structure and protein components (gp5 and gp8).
• Examination of modification strategies (genetic, chemical) for P22 VLPs.

Main Results:

• P22 VLPs possess adaptable structures with varying diameters and pore sizes.
• Extensive modification of P22 capsid and scaffold proteins is achievable.
• Functionalization allows for cargo encapsulation and presentation.

Conclusions:

• Bacteriophage P22 serves as a versatile platform for nanocarrier, nanoreactor, and vaccine development.
• Its tunable morphology and modifiable nature offer significant potential in nanotechnology.
• Further research into P22 VLP applications is warranted.
