Class of enzymes
Lupeol synthase (EC 5.4.99.41 , LUPI , BPW , RcLUS ) is an enzyme with systematic name (3S)-2,3-epoxy-2,3-dihydrosqualene mutase (cyclizing, lupeol-forming) .[ 1] [ 2] [ 3] [ 4] [ 5] [ 6] [ 7] This enzyme catalyses the following chemical reaction
(3S)-2,3-epoxy-2,3-dihydrosqualene
⇌
{\displaystyle \rightleftharpoons }
lupeol
Also forms some beta-amyrin .
