 General Information: Geranylgeranyl pyrophosphate (GGPP) is a crucial compound involved in the biosynthesis of a variety of terpenoids including chlorophylls, carotenoids, tocopherols, plastoquinones, and the plant hormones gibberellins . Moreover, GGPP is also used in posttranslational modifications of proteins (geranylgeranylation) which is important for membrane adhesion as well as the function of some proteins ,. In plants, GGPP is synthesized in two compartments at least: the cytosol and plastids. In both these compartments the formation of GGPP is achieved through the same sequence of reactions. Two pathways have however been created to reflect the differences in origin of the compounds used to form GGPP, and in utilization of GGPP. In the cytosolic pathway (this pathway), the two compounds isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP) originate from the |FRAME:PWY-922|. In plants, cytosolic GGPP is mainly used in the geranylgeranylation of proteins. - aracyc
