In enzymology, a protein geranylgeranyltransferase type II (EC 2.5.1.60) is an enzyme that catalyzes the chemical reaction
- geranylgeranyl diphosphate + protein-cysteine [math]\displaystyle{ \rightleftharpoons }[/math] S-geranylgeranyl-protein + diphosphate
Thus, 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. The systematic name of this enzyme class is geranylgeranyl-diphosphate:protein-cysteine geranyltransferase. Other names in common use include GGTaseII, Rab geranylgeranyltransferase, RabGGTase, geranylgeranyl-diphosphate,geranylgeranyl-diphosphate:protein-, and cysteine geranyltransferase.
