Another study demonstrates how racemic nicotine (mixture of S and R-enantiomers 1 in scheme 3) can be deracemized in a one-pot procedure involving a monoamine oxidase isolated from Aspergillus niger which is able to oxidize only the amine S-enantiomer to the imine 2 and involving an ammonia–borane reducing couple which can reduce the imine 2 back to the amine 1.
His research group is active in the development of fermentative and biocatalytic production processes.
The epsilon subunit is located in the stalk region of the F1 complex, and acts as an inhibitor of the ATPase catalytic core.
