'''GTP-binding proteins''' or '''G proteins''' are transmitting signals outside the cell which cause changes within the cell.  They act as molecular switches which are on when binding GTP and off when binding GDP. GTP-binding proteins belong to two families: heterotrimeric G proteins and small GTPases.  See details on GTP-binding protein LpeD in [[LepA]].
