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 ...

Flagellar Stators Activate a Diguanylate Cyclase To Inhibit Flagellar Stators [PDF]
The bacterial secondary metabolite cyclic di-GMP is a widespread, cytoplasmic signal that promotes a physiological transition in which motility is inhibited and biofilm formation is activated. A paper published in this issue (A. E. Baker, S. S. Webster, A. Diepold, S. L. Kuchma, E.

Presence and analysis of plasmids in human and animal associated Arcobacter species [PDF]
In this study, we report the screening of four Arcobacter species for the presence of small and large plasmids. Plasmids were present in 9.9% of the 273 examined strains.

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.

High levels of cyclic di-GMP in Klebsiella pneumoniae attenuate virulence in the lung [PDF]
The bacterial second messenger bis-(3′-5′)-cyclic dimeric GMP (c-di-GMP) has been shown to influence the expression of virulence factors in certain pathogenic bacteria, but little is known about its activity in the increasingly antibiotic-resistant ...

Nitric Oxide Mediates Biofilm Formation and Symbiosis in Silicibacter sp. Strain TrichCH4B. [PDF]
UnlabelledNitric oxide (NO) plays an important signaling role in all domains of life. Many bacteria contain a heme-nitric oxide/oxygen binding (H-NOX) protein that selectively binds NO.

Distinct chromophore-protein environments enable asymmetric activation of a bacteriophytochrome-activated diguanylate cyclase. [PDF]
Sensing of red and far-red light by bacteriophytochromes involves intricate interactions between their bilin chromophore and the protein environment. The light-triggered rearrangements of the cofactor configuration and eventually the protein conformation enable bacteriophytochromes to interact with various protein effector domains for biological ...
