Acetylacetone-cleaving enzyme is an Fe(II)-dependent dioxygenase catalyzing the first step of acetylacetone degradation in Acinetobacter johnsonii. Acetylacetone is by far the best substrate, but heptane-3,5-dione, octane-2,4-dione, 2-acetylcyclohexanone and ethyl acetoacetate can also act; with pentane-2,4-dione plus O2 it yields acetate and 2-oxopropanal.
