Modifying the stereochemistry of an enzyme-catalyzed reaction by directed evolution [PDF]
Aldolases have potential as tools for the synthesis of stereochemically complex carbohydrates. Here, we show that directed evolution can be used to alter the stereochemical course of the reaction catalyzed by tagatose-1,6-bisphosphate aldolase.
