Stimulates the exchange of guanyl nucleotides associated with a GTPase. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase. Modulates the rate of NTP hydrolysis by a NTPase. Modulates the rate of GTP hydrolysis by a small monomeric GTPase. Modulates the activity of an enzyme. Stops, prevents or reduces the activity of any enzyme that catalyzes the hydrolysis of GTP to GDP and orthophosphate. Increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP. Modulates the rate of GTP hydrolysis by a GTPase.
