Mevalonate pathway with limonene synthesis

The mevalonate (MVA) pathway is one of two independent pathways that is responsible to produce isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) -- the two main precursors to synthesise terpenes. This pathway has seven enzymes to produce IPP and DMAPP, and these compounds are consumed to form geranyl diphosphate (GPP) -- the precursor for the synthesis of monoterpenes such as limonene. In this model, the MVA
