Bacterial rotary export ATPases are allosterically regulated by the nucleotide second messenger cyclic-di-GMP [PDF]

open access: yes, 2015
The widespread second messenger molecule cyclic di-GMP (cdG) regulates the transition from motile and virulent lifestyles to sessile, biofilm-forming ones in a wide range of bacteria. Many pathogenic and commensal bacterial-host interactions are known to

Previously Uncharacterised Aliphatic Amino Acid Positions Modulate the Apparent Catalytic Activity of the EAL Domain of ZMO_1055 and Other Cyclic Di‐GMP‐Specific EAL Phosphodiesterases

open access: yesMicrobial Biotechnology, Volume 19, Issue 2, February 2026.
The A526V substitution, previously not recognised to affect the functionality of the EAL domain, downregulates the apparent catalytic activity of the PAS‐GGDEF‐EAL ZMO1055 phosphodiesterase and other GGDEF‐EAL proteins. Substitution of A526, which is conserved among homologues, with amino acids with longer aliphatic side chains than valine, reverts to ...

Bacillus anthracis edema factor substrate specificity: evidence for new modes of action [PDF]

open access: yes, 2012
Since the isolation of Bacillus anthracis exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only.

Blocking Lysine Crotonylation and Aerobic Glycolysis as Targeting Strategy Against mpox Virus Replication

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
Wei et al. report that MPXV infection induces aerobic glycolysis, a process mediated by the viral protein I3 through lysine crotonylation at its K102 residue. The acetyltransferase MYST1 catalyzes the crotonylation of I3 to inhibit the ubiquitin‐mediated degradation of WDR26.

Stimulator of interferon genes (STING)‐activating nanomedicines: Translating innate immune modulation into effective therapy for triple‐negative breast cancer

open access: yesClinical and Translational Medicine, Volume 16, Issue 1, January 2026.
Graphical representation of STING‐activated nanomedicines is for effective treatment of triple‐negative breast cancer. Abstract Triple‐negative breast cancer (TNBC), marked by profound immunosuppressive complexity, poses a critical challenge in therapy due to the absence of hormone receptors in its phenotype, making it unavailable for conventional ...

Cyclic di-GMP: second messenger extraordinaire [PDF]

open access: yes, 2017
Cyclic dinucleotides (CDNs) are highly versatile signalling molecules that control various important biological processes in bacteria. The best-studied example is cyclic di-GMP (c-di-GMP).

Should the non‐canonical pathway of nitric oxide generation be targeted in hypertensive pregnancies?

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 1, Page 57-69, January 2026.
Abstract Hypertension in pregnancy is prevalent, affecting around 10% of pregnancies worldwide, and significantly increases the risk of adverse outcomes for both mothers and their babies. Current treatment strategies for pregnant women with hypertension are limited, and new approaches for the management of hypertension in pregnancy are urgently needed.

Regulation of the G2/M Transition in Rodent Oocytes [PDF]

open access: yes, 2010
Regulation of maturation in meiotically competent mammalian oocytes is a complex process involving the carefully coordinated exchange of signals between the somatic and germ cell compartments of the ovarian follicle via paracrine and cell–cell coupling ...

Research Progress on Salvia miltiorrhiza Bioactive Components Regulating P‐Selectin for Microcirculatory Improvement: Potential Implications in Acute Pancreatitis

open access: yesMediators of Inflammation, Volume 2026, Issue 1, 2026.
Severe acute pancreatitis (SAP) is associated with high morbidity and mortality. Microcirculatory dysfunction is a critical pathological event in this process and a primary contributor to organ failure (OF). Despite the pivotal role of P‐selectin in mediating the adhesion of activated platelets and leukocytes to the vascular endothelium, a process ...

Cyclic nucleotide-gated channels: structural basis of ligand efficacy and allosteric modulation [PDF]

open access: yes, 1997
Most working proteins, including metabolic enzymes, transcription regulators, and membrane receptors, transporters, and ion channels, share the property of allosteric coupling. The term 'allosteric' means that these proteins mediate indirect interactions
