摘要： The invention describes a process for preparing acetone starting from acetyl-coenzyme A comprising process steps A. enzymatic conversion of acetyl-CoA into acetoacetyl-CoA B. enzymatic conversion of acetoacetyl-CoA into acetoacetate and CoA and C. decarboxylation of acetoacetate to acetone and CO2, which is characterized in that the coenzyme A is not transferred in process step B to an acceptor molecule. In addition, process step B is surprisingly catalysed by enzymes of the classes of acyl-CoA thioesterase, acyl-CoA synthetase or acyl-CoA thiokinase.A completely novel metabolic pathway is concerned, because the enzymatic hydrolysis of acetoacetyl-CoA without simultaneous transfer of CoA to a receptor molecule has never previously been described for any microbial enzyme.
