In enzymology a geranylgeranylglycerol-phosphate geranylgeranyltransferase (EC 2.5.1.42) is an enzyme that catalyzes the chemical reactiongeranylgeranyl diphosphate + sn-3-O-(geranylgeranyl)glycerol 1-phosphate diphosphate + 23-bis-O-(geranylgeranyl)glycerol 1-phosphateThus the two substrates of this enzyme are geranylgeranyl diphosphate and sn-3-O-(geranylgeranyl)glycerol 1-phosphate whereas its two products are diphosphate and 23-bis-O-(geranylgeranyl)glycerol 1-phosphate.This enzyme belongs to the family of transferases specifically those transferring aryl groups or alkyl groups other than methyl groups.
