Abstract

A method based on temperature-conditional resistance to thymineless death has been designed to facilitate the isolation of amino acid-activating enzyme mutants. This method may be modified to obtain a greater or lesser proportion of activating enzyme mutants. In the latter instance, an increased proportion of temperature-sensitive macromolecule mutants of other types is obtained. Additional uses of this procedure are discussed.
