AACT: acetyl-CoA C-acetyltransferase; HMGS: 3-hydroxy-3-methylglutaryl-CoA synthase; HMGCoA: 3-hydroxy-3-methylglutaryl-CoA; HMGR: 3-hydroxy-3-methylglutaryl-CoA reductase; MVK: mevalonate kinase; MVP: mevalonate phosphate; PMK: phosphomevalonate kinase; MVPP: diphosphomevalonate; MVD: mevalonate diphosphate decarboxylase; IPP: isopentenyl diphosphate; DMAPP: dimethylallyl diphosphate; IDI: isopentenyl-diphosphate delta-isomerase; FPS: farnesyl diphosphate synthase; FPP: farnesyl diphosphate; SS: squalene synthase; SE: squalene epoxidase; β-AS: β-amyrin synthase; DDS: dammarenediol synthase; LAS: lanosterol synthase; CAS: cycloartenol synthase; OAS: oleanolic acid synthase; PPDS: protopanaxadiol synthase; PPTS: protopanaxatriol synthase.
