Gtp physiology
WebThe G s alpha subunit of the stimulated G protein complex exchanges GDP for GTP and is released from the complex. [4] In a cAMP-dependent pathway, the activated G s alpha subunit binds to and activates an enzyme called adenylyl cyclase, which, in turn, catalyzes the conversion of ATP into cyclic adenosine monophosphate (cAMP). [5] WebMar 30, 2024 · The context of the physiology and the developmental state of a plant or organ has a considerable role to play (Sablowski & Gutierrez, 2024; ... ROP2 is a small GTPase that is regulated by the binding of GTP (active) or GDP, which is dependent on the activity of ROP-GEF (GDP/GTP exchange factors), ROP-GAP (GTPase activating …
