Abstract: Carboxydotrophic acetogenic microorganisms do not produce MEK and/or 2-butanol. They lack the biosynthesis pathways to make these products. In addition, they produce the intermediate (R,R)-2,3-butanediol whereas the production of MEK and 2-butanol requires production of the intermediate (R,S)-2,3-butanediol. Nonetheless, the production of MEK and/or 2-butanol can be accomplished using recombinant microorganisms adapted to express or overexpress key enzymes in the MEK and/or 2-butanol biosynthesis pathways. Such microorganisms, such as the carboxydotrophic acetogen Clostridium autoethanogenum, can ferment substrates comprising CO. The overall scheme involves the production of 2-butanol from (R,S)-2,3-butanediol and the conversion of (R)-acetoin to (S)-2,3-butanediol. These steps are involved in the production of both MEK and 2-butanol. Such fermentation methods offer a means of using carbon monoxide from industrial processes which would otherwise be released into the atmosphere and pollute the environment.

Abstract: The invention concerns a polypeptide which can be isolated from the Brassicaceae family and which has at least the activity of a hydroxynitrile lyase (HNL). The hydroxynitrile lyase of the invention is the first HNL from the Brassicaceae family. The plants (Arabidopsis) from which this enzyme or its gene is isolated is also described as non-cyanogenic. All HNL-containing plants described so far are cyanogenic plants and so it has until now been assumed that only cyanogenic plants contain hydroxynitrile lyases. Surprisingly, it transpires that a polypeptide (AtHNL) of the invention is (R)-selective. The amino acid sequence gives a theoretical molecular weight of 29.2 kDa for the AtHNL subunit. The calculated molecular mass of the protein of approximately 30 kDa can be confirmed by SDS gel electrophoresis.
