Anaerobic ethylbenzene metabolism in the betaproteobacterium Aromatoleum aromaticum is initiated by anaerobic oxidation to acetophenone via (S)-1-phenylethanol. The subsequent carboxylation of acetophenone to benzoylacetate is catalyzed by an acetophenone-induced enzyme, which has been purified and studied. The same enzyme is involved in acetophenone metabolism in the absence of ethylbenzene. Acetophenone carboxylase consists of five subunits with molecular masses of 70, 15, 87, 75, and 34 kDa… CONTINUE READING
