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 LepA in LepA. An activated G protein-coupled receptor (human β-2 adrenergic receptor in blue ) in a complex with a heterotrimeric G protein (3 subunits:reddish to orange-brown) and hormone (gold) (3sn6), resolution 3.2Å. The boundaries of the membrane in which the GPCR sits are represented in light green.
