[Enzymatic biocatalysis in chemical synthesis of pharmaceuticals].

In this review we summarize the available research on enzymatic biocatalysis in the chemical synthesis of drugs. We focus on oxydoreductsases, particularly ketoreductases, that are widely used in biotechnological processes: alpha- and omega-transaminases, lipases, nitrile hydrolases, and aldolases. The potential for the extended use of novel enzymes produced via bioengineering is discussed.
