Abstract
Geranylgeranyl diphosphate (GGPP) synthase (GGPPSase) catalyzes the synthesis of GGPP, which is an important molecule responsible for the C20-prenylated protein biosynthesis and for the regulation of a nuclear hormone receptor (LXR.RXR). The human GGPPSase cDNA encodes a protein of 300 amino acids which shows 16% sequence identity with the known human farnesyl diphosphate (FPP) synthase (FPPSase). The GGPPSase expressed in Escherichia coli catalyzes the GGPP formation (240 nmol/min/mg) from FPP and isopentenyl diphosphate. The human GGPPSase behaves as an oligomeric molecule with 280 kDa on a gel filtration column and cross-reacts with an antibody directed against bovine brain GGPPSase, which differs immunochemically from bovine brain FPPSase. Northern blot analysis indicates the presence of two forms of the mRNA.Entities:
