Uncoupling conformational change from GTP hydrolysis in a heterotrimeric G protein α-subunit

Heterotrimeric G protein α (Gα) subunits possess intrinsic GTPase activity that leads to functional deactivation with a rate constant of ≈2 min(-1) at 30°C. GTP hydrolysis causes conformational changes in three regions of Gα, including Switch I and Switch II. Mutation of G202→A in Switch II of Gα(i1...
