  • 1,3-dicarbonyl-dioxygenase—a new c-c-bond cleaving enzyme
    Patent number: 6790644
    Abstract: An enzyme that cleaves 1,3-dicarbonyl compounds by incorporating molecular oxygen into the substrate in amounts equimolar to the amount of substrate cleaved. The enzyme from Acinetobacter johnsonii is a multimer of about 67 kilodaltons made up of subunits of about 16.6 kilodaltons. Nucleotide and amino acid sequence analysis of a cloned A. johnsonii subunit indicates little homology with other proteins. Native or recombinant enzyme can be used to decontaminate or detoxify acetylacetone or related diketones.
