Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With 2-oxoglutarate as one donor, and incorporation of one atom of oxygen into each donor
Contains nonheme iron. Catalyses three separate oxidative reactions in the pathway for the biosythesis of the beta-lactamase inhibitor clavulanate in Streptomyces clavuligerus. The first step (hydroxylation) is separated from the latter two (oxidative cyclization and desaturation) by the action of EC 3.5.3.22, proclavaminate amidinohydrolase. The three reactions are all catalysed at the same nonheme iron site.
