Clavaminic acid synthase from Streptomyces clavuligerus is an FeII /2-oxoglutarate-dependent dioxygenase, crucial for the biosynthesis of the β-lactamase inhibitor clavulanic acid. It catalyses three consecutive oxidative reactions, that is, hydroxylation, cyclisation and desaturation, in a single binding cavity. As follows from the results of this QM/MM study, CAS versatility and selectivity depends on the binding cavity, which interplays differently with the substrate for each reaction. The enzyme-substrate interac
