Guanylyl cyclase second messenger
WebCyclic guanosine monophosphate ( cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP. Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane -impermeable peptide hormones to the external cell surface. WebMay 23, 2007 · Introduction. Guanylyl cyclases (GCs) have been identified in many diverse prokaryotes and eukaryotes where they catalyse the formation of the second messenger guanosine 3′,5′-cyclic monophosphate (cGMP) from guanosine 5′-triphosphate (GTP) .In higher plants cGMP has been shown to act as a second messenger in a large number …
