Reaction: (1) deoxyamidinoproclavaminate + 2-oxoglutarate + O2 = amidinoproclavaminate + succinate + CO2
(2) proclavaminate + 2-oxoglutarate + O2 = dihydroclavaminate + succinate + CO2 + H2O
(3) dihydroclavaminate + 2-oxoglutarate + O2 = clavaminate + succinate + CO2 + H2O

Other name(s): clavaminate synthase 2; clavaminic acid synthase
Systematic name: deoxyamidinoproclavaminate,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating)
Comments: Contains nonheme iron. Catalyses three separate oxidative reactions in the pathway for the biosythesis of the β-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 126.96.36.199, proclavaminate amidinohydrolase. The three reactions are all catalysed at the same nonheme iron site.
