Procedures by which nonrandom single-site changes are introduced into structural genes (site-specific mutagenesis) in order to produce mutant genes which can be coupled to promoters that direct the synthesis of a specifically altered protein, which is then analyzed for structural and functional properties and then compared with the predicted and sought-after properties. The design of the protein may be assisted by computer graphic technology and other advanced molecular modeling techniques.
