Abstract

Described is a method for the production isoamyl alcohol (3-methylbutan-1-ol) comprising the enzymatic conversion of 3-methylbutyryl-CoA (isovaleryl-CoA) into isoamyl alcohol comprising: (a) two enzymatic steps comprising (i) first the enzymatic conversion of 3-methylbutyryl-CoA into 3-methylbutyraldehyde (3-methylbutanal or isovaleraldehyde); and (ii) then enzymatically converting the thus obtained 3-methylbutyraldehyde into said isoamyl alcohol; or (b) a single enzymatic reaction in which 3-methylbutyryl-CoA is directly converted into isoamyl alcohol by making use of an alcohol-forming short chain acyl-CoA dehydrogenase/fatty acyl-CoA reductase or an alcohol-forming fatty acyl-CoA reductase (long-chain acyl-CoA:NADPH reductase) (EC 1.2.1.84). Further, described is the above method wherein the 3-methylbutyryl-CoA can be provided by the enzymatic conversion of 3-methylcrotonyl-CoA into said 3-methylbutyryl-CoA. It is also described that the thus obtained isoamyl alcohol can be further enzymatically converted into 3-methylbutyl acetate (isoamyl acetate) as described herein. Described are also recombinant organisms or microorganisms which are capable of performing the above enzymatic…
