Modification of a bi-functional diguanylate cyclase-phosphodiesterase to efficiently produce cyclic diguanylate monophosphate

open access: yesBiotechnology Reports, 2015
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.

Activation mechanism of a small prototypic Rec-GGDEF diguanylate cyclase [PDF]

open access: yesNature Communications, 2021
As part of two-component systems, diguanylate cyclases (DGCs) are activated by phosphorylation. Structural and computational analyses of DgcR, a model DGC, reveal the phosphorylation-induced conformational changes and the activation mechanism likely ...

Phosphorylation-independent regulation of the diguanylate cyclase WspR.

open access: yesPLoS Biology, 2008
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.

Specific Control of Pseudomonas aeruginosa Surface-Associated Behaviors by Two c-di-GMP Diguanylate Cyclases [PDF]

open access: yesmBio, 2010
The signaling nucleotide cyclic diguanylate (c-di-GMP) regulates the transition between motile and sessile growth in a wide range of bacteria. Understanding how microbes control c-di-GMP metabolism to activate specific pathways is complicated by the ...

Probing the activity of diguanylate cyclases and c-di-GMP phosphodiesterases in real-time by CD spectroscopy [PDF]

open access: yesNucleic Acids Research, 2013
Bacteria react to adverse environmental stimuli by clustering into organized communities called biofilms. A remarkably sophisticated control system based on the dinucleotide 3′–5′ cyclic diguanylic acid (c-di-GMP) is involved in deciding whether to form ...

Structure and signaling mechanism of a zinc-sensory diguanylate cyclase [PDF]

open access: yesStructure, 2013
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.

Intact and mutated Shigella diguanylate cyclases increase c-di-GMP [PDF]

open access: yesJournal of Biological Chemistry
The intracellular human pathogen Shigella invades the colonic epithelium to cause disease. Prior to invasion, this bacterium navigates through different environments within the human body, including the stomach and the small intestine. To adapt to changing environments, Shigella uses the bacterial second messenger cyclic di-GMP (c di-GMP) signaling ...

Systematic Analysis of Diguanylate Cyclases That Promote Biofilm Formation by Pseudomonas fluorescens Pf0-1 [PDF]

open access: yesJournal of Bacteriology, 2011
Cyclic di-GMP (c-di-GMP) is a broadly conserved, intracellular second-messenger molecule that regulates biofilm formation by many bacteria. The synthesis of c-di-GMP is catalyzed by diguanylate cyclases (DGCs) containing the GGDEF domain, while its ...

Bordetella bronchiseptica diguanylate cyclase BdcB inhibits the type three secretion system and impacts the immune response [PDF]

open access: yesScientific Reports, 2023
Bordetella bronchiseptica is a gram-negative bacterium that causes respiratory diseases in different animals, including mice, making B. bronchiseptica the gold-standard model to investigate host–pathogen interaction at the molecular level.
