Encapsulation of Active Enzymes within Bacteriophage P22 Virus-Like Particles.

Virus-like particles (VLPs) are nonpathogenic protein cage structures derived from viral coat proteins that have found utility in the area of biomaterials and nanotechnology. VLPs have been exploited as containers for the sequestration and encapsulation of a wide range of guest molecules in their hollow interiors. The robust nature of VLPs lend them as versatile scaffolds that can be exploited to provide protection to encapsulated guest molecules, such as enzymes which are often susceptible to inactivation and degradation, and for organization and construction of new nanomaterials incorporating the chemical properties of the guest molecules. In this chapter a background and methodology for the encapsulation of enzymes on the interior of the bacteriophage P22 derived VLP is described.
