Enzyme Information
| 2.5.1.60 |
Protein geranylgeranyltransferase type II.
based on mapping to UniProt Q08603
Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl- protein + diphosphate.
-!- This enzyme, along with EC 2.5.1.58 and EC 2.5.1.59, constitutes the protein prenyltransferase family of enzymes. -!- Attaches geranylgeranyl groups to two C-terminal cysteines in Ras- related GTPases of a single family, the Rab family (Ypt/Sec4 in lower eukaryotes) that terminate in XXCC, XCXC and CCXX motifs. -!- Reaction is entirely dependent on the Rab substrate being bound to Rab escort protein (REP). -!- Post-translational modification with the geranylgeranyl moiety is essential for Rab GTPases to be able to control the processes of membrane docking and fusion.
