Activation and polar sequestration of PopA, a c-di-GMP effector protein involved in Caulobacter crescentus cell cycle control [PDF]

, 2014
When Caulobacter crescentus enters S-phase the replication initiation inhibitor CtrA dynamically positions to the old cell pole to be degraded by the polar ClpXP protease.

YybT Is a Signaling Protein That Contains a Cyclic Dinucleotide Phosphodiesterase Domain and a GGDEF Domain with ATPase Activity [PDF]

Journal of Biological Chemistry, 2010
The cyclic dinucleotide c-di-AMP [corrected] synthesized by the diadenylate cyclase domain was discovered recently [corrected] as a messenger molecule for signaling DNA breaks in Bacillus subtilis. By searching bacterial genomes, we identified a family of DHH/DHHA1 domain proteins (COG3387) that co-occur with a subset of the diadenylate cyclase domain ...

The Role of Cellulose and O-Antigen Capsule in the Colonization of Plants by Salmonella enterica

Molecular Plant-Microbe Interactions, 2007
Numerous salmonellosis outbreaks have been associated with vegetables, in particular sprouted seed. Thin aggregative fimbriae (Tafi), a component of the extracellular matrix responsible for multicellular behavior, are important for Salmonella enterica ...

Identification of c-di-GMP Signaling Components in Xanthomonas oryzae and Their Orthologs in Xanthomonads Involved in Regulation of Bacterial Virulence Expression

Frontiers in Microbiology, 2019
Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial leaf blight of rice, one of the most devastating bacterial diseases of this staple crop worldwide. Xoo produces a range of virulence-related factors to facilitate its pathogenesis in rice, however, the

The HD-GYP Domain, Cyclic Di-GMP Signaling, and Bacterial Virulence to Plants

Molecular Plant-Microbe Interactions, 2006
Cyclic di-GMP is an almost ubiquitous second messenger in bacteria that was first described as an allosteric activator of cellulose synthase but is now known to regulate a range of functions, including virulence in human and animal pathogens. Two protein

More than Enzymes That Make or Break Cyclic Di-GMP—Local Signaling in the Interactome of GGDEF/EAL Domain Proteins of Escherichia coli

mBio, 2017
The bacterial second messenger bis-(3′-5′)-cyclic diguanosine monophosphate (c-di-GMP) ubiquitously promotes bacterial biofilm formation. Intracellular pools of c-di-GMP seem to be dynamically negotiated by diguanylate cyclases (DGCs, with GGDEF domains)

Fur Represses Vibrio cholerae Biofilm Formation via Direct Regulation of vieSAB, cdgD, vpsU, and vpsA-K Transcription

Frontiers in Microbiology, 2020
Attached Vibrio cholerae biofilms are essential for environmental persistence and infectivity. The vps loci (vpsU, vpsA-K, and vpsL-Q) are required for mature biofilm formation and are responsible for the synthesis of exopolysaccharide.

Identification, activity and disulfide connectivity of C-di-GMP regulating proteins in Mycobacterium tuberculosis. [PDF]

PLoS ONE, 2010
C-di-GMP, a bacterial second messenger plays a key role in survival and adaptation of bacteria under different environmental conditions. The level of c-di-GMP is regulated by two opposing activities, namely diguanylate cyclase (DGC) and phosphodiesterase
