Cyclic di-GMP sginaling
Intro
Diguanylate cyclases
User:Tilman Schirmer/Sandbox 201
The condensation reaction 2 GTP -> c-di-GMP + 2 PPi is catalyzed by GGDEF domains that typically occur in combination with sensory or regulator domains. The structures of two diguanylate cyclases have been determined, both being response regulators with a response regulator receiver (Rec) and a GGDEF output (effector) domain. Response regulators are activated through phosphorylation of a conserved aspartate by cognate histidine kinases.
