ID 1.13.11.50 DE acetylacetone-cleaving enzyme. AN acetylacetone dioxygenase. AN diketone cleaving dioxygenase. AN diketone cleaving enzyme. CA acetylacetone + O2 = acetate + H(+) + methylglyoxal. CC -!- Forms the first step in the acetylacetone degradation pathway of CC Acinetobacter johnsonii. CC -!- While acetylacetone is by far the best substrate, heptane-3,5-dione, CC octane-2,4-dione, 2-acetylcyclohexanone and ethyl acetoacetate can CC also act as substrates. DR Q8GNT2, DKE1_ACIJO ; //
