(3S)-oxidosqualene

tirucalla-7,24-dien-3beta-ol

Arabidopsis thaliana

716418

the enzyme LUP5 makes a 2:2:1 product ratio of tirucalla-7,24-dien-3beta-ol, isotirucallol, and (1S,4S,8beta,9beta,13alpha,14beta,17alpha,20S)-9,10,14-trimethyl-4,9-cyclo-9,10-secocholesta-5,24-dien-1-ol, with minor products including butyrospermol, tirucallol, and 13betaH-malabarica-14(27),17,21-trien-3beta-ol, the enzyme PEN3 produces 85% tirucalla-7,24-dien-3beta-ol and several minor products (6% butyrospermol, 6% tirucallol, 1.5% isotirucallol, 1% 13betaH-malabarica-14(27),17,21-trien-3beta-ol, and 0.5% dammara-20,24-dien-3beta-ol)
