A Symphony of Cyclases: Specificity in Diguanylate Cyclase Signaling [PDF]
Cyclic diguanylate (c-di-GMP) is a near universal signaling molecule produced by diguanylate cyclases that can direct a variety of bacterial behaviors. A major area of research over the last several years has been aimed at understanding how a cell with dozens of diguanylate cyclases can deploy a given subset of them to produce a desired phenotypic ...

Phosphorylation-independent regulation of the diguanylate cyclase WspR.
Environmental signals that trigger bacterial pathogenesis and biofilm formation are mediated by changes in the level of cyclic dimeric guanosine monophosphate (c-di-GMP), a unique eubacterial second messenger.

Cyclic-diGMP is a bacterial messenger that regulates many physiological processes, including many attributed to pathogenicity. Bacteria synthesize cyclic-diGMP from GTP using diguanylate cyclases; its hydrolysis is catalyzed by phosphodiesterases.

Evaluation and characterization of the predicted diguanylate cyclase‐encoding genes in Pseudomonas aeruginosa [PDF]
Opportunistic pathogen Pseudomonas aeruginosa can cause acute and chronic infections in humans. It is notorious for its resistance to antibiotics due to the formation of biofilms.

Structural basis for activation of a diguanylate cyclase required for bacterial predation in Bdellovibrio [PDF]
The initiation of prey invasion by the predatory bacterium Bdellovibrio bacteriovorus is governed by the activity of the diguanlylate cyclase DgcB. Here the authors show that the stimulus regulating DgcB activity is a phosphopeptide derived from DgcB ...

Structure and Signaling Mechanism of a Zinc-Sensory Diguanylate Cyclase [PDF]
Diguanylate cyclases synthesize the second messenger c-di-GMP, which in turn governs a plethora of physiological processes in bacteria. Although most diguanylate cyclases harbor sensory domains, their input signals are largely unknown. Here, we demonstrate that diguanylate cyclase DgcZ (YdeH) from Escherichia coli is regulated allosterically by zinc ...

Diguanylate Cyclase Activation: It Takes Two [PDF]
Characterization of an activated diguanylate cyclase reported in this issue of Structure by Wassmann et al. (2007) reveals how phosphorylation promotes dimerization necessary for synthesis of the second messenger c-di-GMP, establishes the catalytic mechanism, and identifies a widely conserved mode of product inhibition.

Activation of the Diguanylate Cyclase PleD by Phosphorylation-mediated Dimerization [PDF]
Diguanylate cyclases (DGCs) are key enzymes of second messenger signaling in bacteria. Their activity is responsible for the condensation of two GTP molecules into the signaling compound cyclic di-GMP. Despite their importance and abundance in bacteria, catalytic and regulatory mechanisms of this class of enzymes are poorly understood.

The importance of conserved amino acids in heme-based globin-coupled diguanylate cyclases.
Globin-coupled diguanylate cyclases contain globin, middle, and diguanylate cyclase domains that sense O2 to synthesize c-di-GMP and regulate bacterial motility, biofilm formation, and virulence.

The thermosensory diguanylate cyclase (tdcA)
Biofilm production in Pseudomonas aeruginosa is regulated by the intracellular secondary messenger cyclic diguanylate (c-di-GMP). C-di-GMP is produced by diguanylate cyclases (DGCs) and degraded by phosphodiesterases (PDEs). C-di-GMP controls motility, biofilm formation and virulence factor production in many bacteria.
