An HD-GYP Cyclic Di-Guanosine Monophosphate Phosphodiesterase with a Non-Heme Diiron–Carboxylate Active Site

, 2016
The intracellular level of the ubiquitous bacterial secondary messenger, cyclic di-(3′,5′)-guanosine monophosphate (c-di-GMP), represents a balance between its biosynthesis and degradation, the latter via specific phosphodiesterases (PDEs).

Assessing Spatiotemporal Side Effects of Diversionary Feeding on Mesopredators

Animal Conservation, EarlyView.
We tested whether diversionary feeding alters the space use, aggregation, or activity patterns of mesopredators using a treatment‐control design with camera traps. Although both species frequently used feeding stations, diversionary feeding did not significantly affect their spatial distribution, aggregation, or temporal behaviour.

Finally! The structural secrets of a HD‐GYP phosphodiesterase revealed [PDF]

Molecular Microbiology, 2013
SummaryThe major sessility‐motility lifestyle change and additional fundamental aspects of bacterial physiology, behaviour and morphology are regulated by the secondary messenger cyclic di‐GMP (c‐di‐GMP). Although the c‐di‐GMP metabolizing enzymes and many receptors have been readily characterized upon discovery, the HD‐GYP domain c‐di‐GMP ...

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility

Molecular Microbiology, EarlyView.
Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...

The MarR Family Transcriptional Regulator EmrR Negatively Regulates the Type III Secretion System (T3SS) and Positively Modulates Pathogenicity in Dickeya oryzae

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Effect of Fish Meal Replacement by Complex Protein on Growth Performance, Metabolism, and Health of Triploid Rainbow Trout (Oncorhynchus mykiss)

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
A comprehensive investigation was conducted to evaluate dietary fish meal (FM) replacement by a complex protein blend composed of soybean meal, soybean protein concentrate, corn gluten meal, wheat gluten, and blood cell powder in triploid rainbow trout (Oncorhynchus mykiss). Five isonitrogenous (46% crude protein) and isolipidic (24% crude lipid) diets

The HD‐GYP domain of RpfG mediates a direct linkage between the Rpf quorum‐sensing pathway and a subset of diguanylate cyclase proteins in the phytopathogen Xanthomonas axonopodis pv citri [PDF]

Molecular Microbiology, 2006
SummaryBacteria use extracellular levels of small diffusible autoinducers to estimate local cell‐density (quorum‐sensing) and to regulate complex physiological processes. The quorum‐sensing signal transduction pathway of Xanthomonas spp. phytopathogens has special features that distinguish it from that of other pathogens. This pathway consists of RpfF,

The Diverse Roles of the Histone‐Like Nucleoid Structuring (H‐NS) Protein in Vibrio parahaemolyticus

Genetics Research , Volume 2026, Issue 1, 2026.
The histone‐like nucleoid structuring (H‐NS) protein is a global transcriptional regulator critical for bacterial genome organization and gene expression. In Vibrio parahaemolyticus, H‐NS represses virulence factors such as thermostable direct hemolysin (TDH), type III secretion systems (T3SS1/T3SS2), and type VI secretion systems (T6SS1/T6SS2).
