title: Protein engineering 20 years on.
abstract: It is 20 years since site-directed mutagenesis was first used to modify the active site of an enzyme of known structure and mechanism. Since then, this method has contributed far-reaching insights into catalysis, specificity, stability and folding of proteins. Engineered proteins are now being used in industry and for the improved treatment of human disease.
