GPP is an intermediate in the
isoprenoid biosynthesis pathway that produces longer prenyl chains such as
farnesyl pyrophosphate and
geranylgeranyl pyrophosphate as well as many
terpenes. It can be prepared in the laboratory from geraniol. (IPP) and
dimethylallyl pyrophosphate (DMAPP) are condensed by geranyl pyrophosphate synthase (
dimethylallyltranstransferase) to produce geranyl pyrophosphate (GPP) and pyrophosphate. The carbon skeletons of DMAPP and IPP have been colored to indicate their location in GPP. ==Microbial toxicity==
