additional information
enzyme catalyzes both the hydroxylation of hyoscyamine, reaction of EC 1.14.11.11, and the epoxidation of 6beta-hydroxyhyoscyamine to generate scopolamine. Epoxidase activity is low compared to the hydroxylase activity. The binding of the substrates, hyoscyamine and 2-oxoglutarate, to the enzyme induces significant conformational changes
