Compartmentation of Isoprenoid Biosynthesis in the Plant Cell.

The mevalonate pathway is active in the cytosol (and supplies IPP to mitochondria), whereas the methylerythritol 4-phosphate (MEP) pathway is active in plastids. Enzymatic steps similar in both the cytosolic and plastidic pathways are represented in the common area. GGPP, geranylgeranyl diphosphate.
