Achilleol B synthase - Misplaced Pages

Achilleol B synthase (EC 5.4.99.48) is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, achilleol-B-forming). This enzyme catalyses the following chemical reaction

(3S)-2,3-epoxy-2,3-dihydrosqualene

\rightleftharpoons

achilleol B

Achilleol B is probably formed by cleavage of the 8-14 and 9-10 bonds of (3S)-2,3-epoxy-2,3-dihydrosqualene.
