Cyclic di-GMP as a bacterial second messenger.
Environmental signals trigger changes in the bacterial cell surface, including changes in exopolysaccharides and proteinaceous appendages that ultimately favour bacterial persistence and proliferation. Such adaptations are regulated in diverse bacteria by proteins with GGDEF and EAL domains. These proteins are predicted to regulate cell surface adhesiveness by controlling the level of a second ...
متن کاملYC-1 potentiates nitric oxide- and carbon monoxide-induced cyclic GMP effects in human platelets.
Nitric oxide (NO), the physiological activator of soluble guanylyl cyclase (sGC), induces inhibitory effects on platelet activation via elevation of cGMP levels and stimulation of the cGMP-dependent protein kinase. YC-1, a benzylindazole derivative, was shown to activate sGC in intact platelets, resulting in inhibition of platelet aggregation. In a previous study, we demonstrated that YC-1 not ...
متن کاملRiboswitches in eubacteria sense the second messenger cyclic di-GMP.
Cyclic di-guanosine monophosphate (di-GMP) is a circular RNA dinucleotide that functions as a second messenger in diverse species of bacteria to trigger wide-ranging physiological changes, including cell differentiation, conversion between motile and biofilm lifestyles, and virulence gene expression. However, the mechanisms by which cyclic di-GMP regulates gene expression have remained a myster...
متن کاملInhibition of cyclic GMP-binding cyclic GMP-specific phosphodiesterase (Type 5) by sildenafil and related compounds.
The cGMP-binding cGMP-specific phosphodiesterase (PDE5) degrades cGMP and regulates the intracellular level of cGMP in many tissues, including the smooth muscle of the corpus cavernosum of the penis. Sildenafil (Viagra), a specific PDE5 inhibitor, promotes penile erection by blocking the activity of PDE5, which causes cGMP to accumulate in the corpus cavernosum. In the present study, sildenafil...
متن کاملCarbon Monoxide: An Endogenous Modulator of the Nitric Oxide–Cyclic GMP Signaling System
Carbon monoxide (CO) is an activator of soluble guanylyl cyclase and is implicated as a neuronal messenger. CO production, nitric oxide synthase (NOS) activity, and guanosine 3',5'-monophosphate (cGMP) levels were quantitated in cerebellar granule cell cultures. Metabolic labeling experiments enabled the direct measurement of neuronal CO production in vitro. CO production is significant, and pe...
