SYSTEMATIC NAME
IUBMB Comments
acetylacetone:oxygen oxidoreductase
An Fe(II)-dependent enzyme. Forms the first step in the acetylacetone degradation pathway of Acinetobacter johnsonii. While acetylacetone is by far the best substrate, heptane-3,5-dione, octane-2,4-dione, 2-acetylcyclohexanone and ethyl acetoacetate can also act as substrates.
