Enzyme Stabilization by Virus-Like Particles.

ABSTRACT: The properties of enzymes packaged within the coat protein shell of virus-like particles (VLPs) were studied to provide a comprehensive assessment of such factors. Such entrainment did not seem to perturb enzyme function, but it did significantly enhance enzyme stability against several denaturing stimuli such as heat, organic solvents, and chaotropic agents. This improvement in performance was found to be general and independent of the number of independent subunits required and of the number of catalytically active enzymes packaged. Packaged enzymes were found by measurements of intrinsic tryptophan fluorescence to retain some of their native folded structure even longer than their catalytic activity, suggesting that protein folding is a significant component of the observed catalytic be
