Clavaminate synthase (EC 1.14.11.21, clavaminate synthase 2, clavaminic acid synthase) is an enzyme with systematic name deoxyamidinoproclavaminate,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating).[1][2][3][4][5] This enzyme catalyses the following chemical 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
Clavaminate synthase contains nonheme iron.
