Chain A ( PGTA_RAT | Q08602)
| molecular function |
| | GO:0017137 | | Rab GTPase binding | | Interacting selectively and non-covalently with Rab protein, any member of the Rab subfamily of the Ras superfamily of monomeric GTPases. |
| | GO:0004663 | | Rab geranylgeranyltransferase activity | | 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. |
| | GO:0004659 | | prenyltransferase activity | | Catalysis of the transfer of a prenyl group from one compound (donor) to another (acceptor). |
| | GO:0008318 | | protein prenyltransferase activity | | Catalysis of the covalent addition of an isoprenoid group such as a farnesyl or geranylgeranyl group via thioether linkages to a cysteine residue in a protein. |
| | GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
| | GO:0008270 | | zinc ion binding | | Interacting selectively and non-covalently with zinc (Zn) ions. |
| biological process |
| | GO:0018344 | | protein geranylgeranylation | | The covalent attachment of a geranylgeranyl group to a protein. |
| | GO:0018342 | | protein prenylation | | The covalent attachment of a prenyl group to a protein; geranyl, farnesyl, or geranylgeranyl groups may be added. |
| cellular component |
| | GO:0005968 | | Rab-protein geranylgeranyltransferase complex | | A heterodimeric enzyme complex, which in mammals is composed of an alpha and a beta subunit, and which associates with an accessory protein Rep (Rab escort protein). Catalyzes of the transfer of a geranyl-geranyl group from geranylgeranyl pyrophosphate to a Rab protein. |
Chain B ( PGTB2_MOUSE | P53612)
| molecular function |
| | GO:0017137 | | Rab GTPase binding | | Interacting selectively and non-covalently with Rab protein, any member of the Rab subfamily of the Ras superfamily of monomeric GTPases. |

Known substrates include Ras-related GTPases of a single family and the Rab family. |
| | GO:0003824 | | catalytic activity | | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0004659 | | prenyltransferase activity | | Catalysis of the transfer of a prenyl group from one compound (donor) to another (acceptor). |
| | GO:0016740 | | transferase activity | | Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor).
