The YfiBNR signal transduction mechanism reveals novel targets for the evolution of persistent Pseudomonas aeruginosa in cystic fibrosis airways [PDF]
The genetic adaptation of pathogens in host tissue plays a key role in the establishment of chronic infections. While whole genome sequencing has opened up the analysis of genetic changes occurring during long-term infections, the identification and ...

Determinants for the Activation and Autoinhibition of the Diguanylate Cyclase Response Regulator WspR [PDF]
The bacterial second messenger bis-(3'-5')-cyclic dimeric guanosine monophosphate (c-di-GMP) controls secretion, cell adhesion, and motility, leading to biofilm formation and increased cytotoxicity. Diguanylate cyclases containing GGDEF and phosphodiesterases containing EAL or HD-GYP domains have been identified as the enzymes controlling cellular c-di-

Identification of a Diguanylate Cyclase and Its Role in Porphyromonas gingivalis Virulence [PDF]
ABSTRACT Porphyromonas gingivalis is a Gram-negative obligate anaerobic bacterium and is considered a keystone pathogen in the initiation of periodontitis, one of the most widespread infectious diseases. Bacterial bis-(3′-5′) cyclic GMP (cyclic di-GMP [c-di-GMP]) serves as a second messenger and is involved in ...

The polysaccharide Bep is essential for in vitro biofilm formation of the opportunistic pathogen Burkholderia cenocepacia. We found that the Burkholderia diffusible signaling factor (BDSF) quorum sensing receptor RpfR is a negative regulator of the bep ...

Bi-modal distribution of the second messenger c-di-GMP controls cell fate and asymmetry during the caulobacter cell cycle [PDF]
Many bacteria mediate important life-style decisions by varying levels of the second messenger c-di-GMP. Behavioral transitions result from the coordination of complex cellular processes such as motility, surface adherence or the production of virulence ...

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.

Insights into the activation mechanism of PopA, a cyclic di-GMP effector protein involved in cell cycle and development of "Caulobacter Crescentus" [PDF]
In Caulobacter crescentus, a complex network integrating cyclic di-GMP and Phosphorylation-dependent signals controls the proteolysis of key regulatory proteins to drive cell cycle and polar morphogenesis.

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 ...
