(+)-Larreatricin hydroxylase

(+)-Larreatricin hydroxylase (EC 1.14.99.47) is an enzyme with systematic name (+)-larreatricin:oxygen 3'-hydroxylase.^[1] This enzyme catalyses the following chemical reaction

(+)-larreatricin + O₂ + AH₂

\rightleftharpoons

(+)-3'-hydroxylarreatricin + A + H₂O

This enzyme is isolated from the plant Larrea tridentata (creosote bush).
