Abstract

This account provides a personal view on the development of biocatalysis over the last two decades. Examples include the use of commercial enzymes, such as lipases, (recombinant) esterases, transaminases, and Baeyer–Villiger monooxygenases for the synthesis of optically pure compounds. The opportunity provided by modern protein engineering methods to tailor design an enzyme for a given scientific problem (substrate scope, selectivity, stability) is emphasized together with concepts to boost this technology in terms of timelines and success.
