Abstract
Gentisate:oxygen 1,2-oxidoreductase (decyclizing) (EC 1.13.11.4; gentisate 1,2-dioxygenase) from Moraxella osloensis was purified to homogeneity as shown by polyacrylamide gel electrophoresis. The enzyme has a molecular weight of about 154,000 and gives rise to subunits of molecular weight 40,000 in the presence of sodium dodecyl sulfate. Gentisate 1,2-dioxygenase showed broad substrate specificity and attacked a range of halogen- and alkyl-substituted gentisic acids. Maleylpyruvate, the product formed from gentisate, was degraded by cell extracts supplemented with reduced glutathione, but substituted maleylpyruvates were not attacked under these conditions.
