STABILIZATION OF HEN EGG WHITE LYSOZYME BY A CAVITY-FILLING MUTATION

Overview

Stabilization of a protein using cavity-filling strategy has hardly been, successful because of unfavorable van der Waals contacts. We succeeded in, stabilizing lysozymes by cavity-filling mutations. The mutations were, checked by a simple energy minimization in advance. It was shown clearly, that the sum of free energy change caused by the hydrophobicity and the, cavity size was correlated very well with protein stability. We also, considered the aromatic-aromatic interaction. It is reconfirmed that the, cavity-filling mutation in a hydrophobic core is a very useful method to, stabilize a protein when the mutation candidate is selected carefully.
