In enzymology a protein geranylgeranyltransferase type II (EC 2.5.1.60) is an enzyme that catalyzes the chemical reactiongeranylgeranyl diphosphate + protein-cysteine S-geranylgeranyl-protein + diphosphateThus the two substrates of this enzyme are geranylgeranyl diphosphate and protein-cysteine whereas its two products are S-geranylgeranyl-protein and diphosphate.This enzyme belongs to the family of transferases specifically those transferring aryl or alkyl groups other than methyl groups.
