Described is a method for the production of 3-buten-2-one comprising the enzymatic conversion of 4-hydroxy-2-butanone into 3-buten-2-one by making use of an enzyme catalyzing 4-hydroxy-2-butanone dehydration, wherein said enzyme catalyzing 4-hydroxy-2-butanone dehydration is (a) a 3-hydroxypropiony-CoA dehydratase (EC 4.2.1.116), (b) a 3-hydroxybutyryl-CoA dehydratase (EC 4.2.1.55), (c) an enoyl-CoA hydratase (EC 4.2.1.17), (d) a 3-hydroxyoctanoyl-[acyl-carrier-protein] dehydratase (EC 4.2.1.59), (e) a crotonyl-[acyl-carrier-protein] hydratase (EC 4.2.1.58), (f) a 3-hydroxydecanoyl-[acyl-carrier-protein] dehydratase (EC 4.2.1.60), (g) a 3-hydroxypalmitoyl-[acyl-carrier-protein] dehydratase (EC 4.2.1.61 ), (h) a long-chain-enoyl-CoA hydratase (EC 4.2.1.74), or (i) a 3-methylglutaconyl-CoA hydratase (EC 4.2.1.18). The produced 3-buten-2-one can be further converted into 3-buten-2-ol and finally into 1,3-butadiene. |
