title: Greatly reduced amino acid alphabets in directed evolution: making the right choice for saturation mutagenesis at homologous enzyme positions.
abstract: Enantioselective mutants of the thermally robust phenyl acetone monooxygenase (PAMO) as catalysts in Baeyer-Villiger reactions have been evolved by utilizing saturation mutagenesis in which drastically reduced amino acid alphabets are employed at homologous enzyme positions.
