A linearized form of cyclic di-GMP
5'-pGpG is a linearized form of cyclic di-GMP, a bacterial second messenger that activates the host innate immune system through stimulator of interferon genes (STING).1,2,3 It is a metabolite of cyclic di-GMP formed via hydrolysis by various phosphodiesterases (PDEs) that binds to the cyclic di-GMP-I riboswitch with reduced affinity compared to cyclic di-GMP.4,5 5'-pGpG is intended for use as a negative control for cyclic di-GMP signaling.
