P1-(5-Guanosyl)-P2-(5-guanosyl)-(35)-diphosphate, Sodium salt
The linear diguanylate pGpG is the first phosphodiesterase-catalyzed hydrolysis product of cylic di-GMP (c-diGMP). C-diGMP has been identified as a novel second messenger in bacteria that triggers various physiological changes such as virulence gene expression or cell differentiation. The role of pGpG in c-diGMP signalling is under investigation.
