Accepted name: achilleol B synthase

Reaction: (3S)-2,3-epoxy-2,3-dihydrosqualene = achilleol B

For diagram of reaction click here.

Systematic name: (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, achilleol-B-forming)

Comments: Achilleol B is probably formed by cleavage of the 8-14 and 9-10 bonds of (3S)-2,3-epoxy-2,3-dihydrosqualene as part of the cyclization reaction, after formation of the oleanane skeleton.
