Di-oxygenases

For these aerobic bacteria, the mono- and di-oxygenase enzymes are generally important to catalyze the incorporation of oxygen from 02 into the aromatic ring of organic compounds prior to ring fission [17].

As shown in Sect. 3, the structure of type 2 copper centers is less uniform than in types 1 and 3. Type 2 copper proteins can, furthermore, neither be phylo-genetically grouped by comparison of amino acid sequences nor by a common tertiary structure. The class of type 2 copper proteins contains oxidases, mono-and di-oxygenases, as well as enzymes, which participate in metabolizing reactive species.
