This enzyme has been successfully altered through several rounds of protein engineering to an enantioselective amine dehydrogenase. Instead of the wild-type alpha-keto acid, the new amine dehydrogenase now accepts the analogous ketone, methyl isobutyl ketone (MIBK), which corresponds to exchange of the carboxy group by a methyl group, to produce chiral (R)-1,3-dimethylbutylamine via a reductive amination reaction. This represents a suitable enzymatic production route for the asymmetric synthesis of amines from prochiral ketones and free ammonia, which is one of the top aspirational reactions challenging the pharmaceutical industry.1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence.
