Structural basis for the inhibition of the Bacillus subtilis c-di-AMP cyclase CdaA by the phosphoglucomutase GlmM [PDF]

open access: yes, 2021
Cyclic-di-adenosine monophosphate (c-di-AMP) is an important nucleotide signaling molecule that plays a key role in osmotic regulation in bacteria. c-di-AMP is produced from two molecules of ATP by proteins containing a diadenylate cyclase (DAC) domain ...

Cyclic di-AMP Is Critical for Listeria monocytogenes Growth, Cell Wall Homeostasis, and Establishment of Infection

open access: yesmBio, 2013
Listeria monocytogenes infection leads to robust induction of an innate immune signaling pathway referred to as the cytosolic surveillance pathway (CSP), characterized by expression of beta interferon (IFN-β) and coregulated genes.

Molecular analysis of adenylyl cyclase: Bacillus anthracis edema factor exotoxin [PDF]

open access: yes, 2010
Bacillus anthracis causes anthrax disease and exerts its deleterious effects by the release of three exotoxins, i.e. lethal factor, protective antigen and edema factor EF), a highly active calmodulin-dependent adenylyl cyclase (AC). However, conventional

Toxin ζ Triggers a Survival Response to Cope with Stress and Persistence

open access: yesFrontiers in Microbiology, 2017
Bacteria have evolved complex regulatory controls in response to various environmental stresses. Protein toxins of the ζ superfamily, found in prominent human pathogens, are broadly distributed in nature.

Control of the Diadenylate Cyclase CdaS in Bacillus subtilis AN AUTOINHIBITORY DOMAIN LIMITS CYCLIC DI-AMP PRODUCTION

open access: yes, 2014
The Gram-positive bacterium Bacillus subtilis encodes three diadenylate cyclases that synthesize the essential signaling nucleotide cyclic di-AMP. The activities of the vegetative enzymes DisA and CdaA are controlled by protein-protein interactions with ...

A network of acetyl phosphate-dependent modification modulates c-di-AMP homeostasis in Actinobacteria

open access: yesmBio
Cyclic purine nucleotides are important signal transduction molecules across all domains of life. 3′,5′-cyclic di-adenosine monophosphate (c-di-AMP) has roles in both prokaryotes and eukaryotes, while the signals that adjust intracellular c-di-AMP and ...

Anti‐Biofilm Properties of Polyurethane Biomaterials Tethered With Small Molecules via Polyethylene Glycol Linker

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 4, April 2026.
Interfering with nucleotide signaling pathways using small molecules represents a promising strategy to disrupt biofilm formation on biomaterial surfaces. This study reported a new approach for tethering small molecules onto polyurethane surfaces using a PEG long linker.

Current status and future perspectives of multi‐modal bacteria‐based cancer therapies

open access: yesClinical and Translational Medicine, Volume 15, Issue 10, October 2025.
Bacteria exhibit inherent tumour‐targeting capabilities, particularly thriving in hypoxic tumour microenvironments (TMEs) and activating potent anti‐tumour immune responses through pathogen‐associated molecular patterns (PAMPs) and immunomodulation.

Activation of a Secondary‐Messenger Receptor via Allosteric Modulation of a Dynamic Conformational Ensemble

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 38, September 15, 2025.
Intrinsically disordered loops within globular protein domains have long escaped structural biology. Here, Söldner et al. show that despite this disorder, an allosteric modulation is exerted in a secondary‐messenger receptor by binding of its secondary messenger.

Resensitizing β‐Lactams by Reprogramming Purine Metabolism in Small Colony Variant for Osteomyelitis Treatment

open access: yesAdvanced Science, Volume 12, Issue 5, February 3, 2025.
This study successfully isolated small colony variant (SCV) strains from osteomyelitis samples and found that alterations in purine metabolism, and consequent increases in antibiotic resistance are typical features of SCV. Based on the finding that regulating purine metabolism can enhance SCV sensitivity to β‐lactams, a co‐delivery system of lonidamine
