Term Name:	Rab geranylgeranyltransferase activity		Search Ontology:
Synonyms:	geranylgeranyl-diphosphate,geranylgeranyl-diphosphate:protein-cysteine geranyltransferase activity GGTase-II activity GGTaseII activity protein geranylgeranyltransferase type II activity Rab-protein geranylgeranyltransferase activity RabGGTase activity type II protein geranyl-geranyltransferase activity
Definition:	Catalysis of the reaction: 2 geranylgeranyl diphosphate + protein-cysteine = 2 S-geranylgeranyl-protein + 2 diphosphate. This reaction is the formation of two thioether linkages between the C-1 atom of the geranylgeranyl groups and two cysteine residues within the terminal sequence motifs XXCC, XCXC or CCXX. Known substrates include Ras-related GTPases of a single family and the Rab family. (2)
