Mutants of Escherichia coli K-12 “Cryptic,” or Deficient in 5′-Nucleotidase (Uridine Diphosphate-Sugar Hydrolase) and 3′-Nucleotidase (Cyclic Phosphodiesterase) Activity [PDF]

open access: yesJournal of Bacteriology, 1973
Mutants of Escherichia coli have been selected for the absence of 5′-nucleotidase (uridine diphosphate-sugar hydrolase) and 3′-nucleotidase (2′,3′-cyclic phophodiesterase). Mutants selected for the absence of 5′-nucleotidase are of two kinds: those that lack detectable activity for the enzyme (Ush −

The Role of Chemistry Across Disciplines From Humanities to Life Sciences in Understanding Complexity and Emergence

open access: yesAngewandte Chemie, Volume 138, Issue 17, 20 April 2026.
This study explores the origins of life by linking prebiotic chemistry, the emergence of information‐carrying molecules such as RNA and proteins, and philosophical questions about consciousness. The study emphasizes the role of molecular evolution in the Central Dogma and provides insights into the chemical origins of biology and the basis of life's ...

Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

open access: yesIntegrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Corynebacterium glutamicum for Microbial Production of Chitin Oligosaccharides Using Modular Engineering

open access: yesFood Bioengineering
Microbial fermentation is a potent strategy for eco‐friendly and sustainable chitin oligosaccharide (CHOS) production. Nonetheless, hurdles (e.g., imbalanced metabolic flow and the need for uridine diphosphate (UDP)‐sugar donor consumption in CHOS ...

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

open access: yesIntegrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Drug-like antagonists of P2Y receptors — from lead identification to drug development [PDF]

open access: yes, 2016
P2Y receptors are expressed in virtually all cells and tissue types and mediate an astonishing array of biological functions, including platelet aggregation, smooth muscle cell proliferation, and immune regulation.

The potential for biased signalling in the P2Y receptor family of GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Effect of Glucose and Galactose Loading in Normal Subjects on Red and White Blood Cell Uridine Diphosphate Sugars

open access: yesBiochemical and Molecular Medicine, 1995
In order to test the assumption that red blood cell (RBC) uridine diphosphate galactose content is regulated in part by dietary galactose and to help comprehend factors influencing RBC and white blood cell (WBC) uridine diphosphate hexose concentrations in vivo, oral loading studies were performed with 50 g of galactose or 75 g of glucose in normal ...

Engineering the bacterial nutrition strategy to control plant diseases

open access: yesJournal of Integrative Plant Biology, EarlyView.
This commentary on Wang et al. (2025) and Phan et al. (2025) highlights previously undiscovered Xanthomonas pathways for nutrition acquisition, explains how Xanthomonas bacteria hijack host molecular machinery through their effector proteins, and discusses how these studies can be used to develop new disease resistance mechanisms.
