Site-directed mutagenesis of acetolactate decarboxylase (ALDC) enzyme
This unusual activity makes ALDC of potential use in asymmetric catalysis where a single enantiomer of product is required, such as in the synthesis of drug molecules, agro-chemicals, food additives etc. The chirality of the molecule can determine the biological response given. A dramatic example of this is the use of thalidomide during pregnancy in the 1960s, the R enantiomer has the desired sedative effect but the S enantiomer is teratogenic and leads to fetal malformations.
