'''Achilleol B synthase''' ({{EC number|5.4.99.48}}) is an [[enzyme]] with system name ''(3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, achilleol-B-forming)''.<ref>{{cite journal | title = Triterpene cyclases from <em>Oryza sativa</em> L.: cycloartenol, parkeol and achilleol B synthases |author = Ito, R., Mori, K., Hashimoto, I., Nakano, C., Sato, T. and Hoshino, T. |journal = Org. Lett. |year = 2011 |volume = 13 |pages = 2678–2681 |pmid = 21526825}}</ref> This enzyme [[catalysis|catalyses]] the following [[chemical reaction]]<br />
<br />
: (3S)-2,3-epoxy-2,3-dihydrosqualene <math>\rightleftharpoons</math> achilleol B<br />
<br />
Achilleol B is probably formed by cleavage of the 8-14 and 9-10 bonds of (3S)-2,3-epoxy-2,3-dihydrosqualene.<br />
