| GTP cyclohydrolase I |

| GTP-binding p. |
any of a number of regulatory proteins, including the G proteins and the monomeric small GTP-binding proteins, in which the exchange of GDP for GTP induces a conformational change to produce an active state, while the hydrolysis of GTP to GDP produces an inactive state. GTP-binding proteins act as switches that couple cell-surface receptor activation with intracellular processes such as protein synthesis.

| GTPase-activating p. |
a protein that stimulates the GTPase activity of a GTP-binding protein, resulting in the conversion of the protein to its inactive form.
