Main steps in the biosynthesis of terpenoids in fungi. The abbreviations used are: HMG-CoA: hydroxymethylglutaryl CoA; MVP: 5-phosphomevalonate; MVPP: 5-diphosphomevalonate; IPP: isopentenyl pyrophosphate; DMAPP: dimethylallyl pyrophosphate; FPP: farnesyl pyrophosphate. Enzymes are indicated in bold; AACT: acetoacetyl-CoA thiolase; HMGS: HMG-CoA synthase; HMGR: HMG-CoA reductase; MVK: mevalonate kinase; PMK: phosphomevalonate kinase; PMD: mevalonate 5-diphosphate decarboxylase; IDI: IPP isomerase; FPS: FPP synthase; SQS: Squalene synthase.
