Abstract

A systemic study of single amino acid substitutions in bacteriophage T4 lysozyme permitted a test of the concept that conserved amino acid residues are more functionally important than nonconserved residues. Substitutions of amino acid residues that are conserved among five bacteriophage-encoded lysozymes were found to lead more frequently to loss of function than substitutions of nonconserved residues. Of 163 residues tested, only 74 (45%) are sensitive to at least one substitution; however, all 14 residues that are fully conserved are sensitive to substitutions.
