Enzyme DgcZ from ''E. coli'' acts a catalyst to synthesize cyclic di-GMP from two substrate guanosine triphosphate (GTP) molecules to aid in communication of signals throughout the bacteria. C-di-GMP is a second messenger in the production of poly-β-1,6-N-acetylglucosamine (poly-GlcNAc), a polysaccharide required for ''E. coli'' biofilm production. This biofilm allows ''E. coli'' to adhere to extracellular surfaces. | Diguanylate cyclases are a group of class 2 transferase enzymes that catalyze the production of cyclic dimeric-guanosine monophosphate (c-di-GMP), an important <span class="plainlinks">[https://en.wikipedia.org/wiki/Second_messenger_system second messenger]</span> for <span class="plainlinks">[https://en.wikipedia.org/wiki/Signal_transduction signal transduction]</span>.
