| Abstract: | Bacterial Rieske non-heme iron dioxygenase catalyzes aromatics in the first step aerobic biodegradation and initiates biodegradation of a number of aromatic or substituted aromatic compounds in aerobic environment, and at the same time it can be used as a synthon for organic compounds. It is a kind of novel and abundant enzyme, possessing great potentials in bioremediation of polluted environment and conforming to "green chemistry". The recent research advances on its classification, crystal structure, mechanism and gene modification are discussed in this paper. Fig 4, Tab 1, Ref 17 |
