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 [math]\displaystyle{ \rightleftharpoons }[/math] amidinoproclavaminate + succinate + CO2
(2) proclavaminate + 2-oxoglutarate + O2 [math]\displaystyle{ \rightleftharpoons }[/math] dihydroclavaminate + succinate + CO2 + H2O
(3) dihydroclavaminate + 2-oxoglutarate + O2 [math]\displaystyle{ \rightleftharpoons }[/math] clavaminate + succinate + CO2 + H2O

Clavaminate synthase contains nonheme iron.
