The molecular structure of Schistosoma mansoni PNP isoform 2 provides insights into the nucleoside selectivity of PNPs.

PLoS ONE, 2018
Purine nucleoside phosphorylases (PNPs) play an important role in the blood fluke parasite Schistosoma mansoni as a key enzyme of the purine salvage pathway. Here we present the structural and kinetic characterization of a new PNP isoform from S. mansoni,

Structure of Escherichia coli AMP Nucleosidase Reveals Similarity to Nucleoside Phosphorylases [PDF]

, 2004
AMP nucleosidase (AMN) catalyzes the hydrolysis of AMP to form adenine and ribose 5-phosphate. The enzyme is found only in prokaryotes, where it plays a role in purine nucleoside salvage and intracellular AMP level regulation.

Biosynthesis and Genetic Tuning of Guanine Crystals via Metabolic Engineering of Yeast

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
We demonstrate how yeast cells can be harnessed as cellular factories for the synthesis of optically functional guanine crystals, where genetic editing is used to tune crystal size, order and optical properties. This demonstrates a powerful new biosynthetic approach for the development of sustainable and biocompatible optical pigments, which utilizes ...

The Peculiar Case of the Hyperthermostable Pyrimidine Nucleoside Phosphorylase from Thermus Thermophilus [PDF]

, 2020
The poor solubility of many nucleoside and nucleobases in aqueous solution demands harsh reaction conditions (base, heat, cosolvent) in nucleoside phosphorylase-catalyzed processes to facilitate substrate loading beyond the low millimolar range. This, in

Ribonucleotides Amplify Mitochondrial DNA‐Driven cGAS–STING Activation via FdUMP‐ribonucleotide Hybrid Particles to Potentiate Chemoimmunotherapy

Advanced Science, EarlyView.
This work develops a metabolic sharing strategy that employs cytidine monophosphate (CMP) to competitively reprogram floxuridine (FUDR) pyrimidine metabolism in colorectal tumor cells. Elevated intracellular FdUMP induces nucleotide imbalance, drives mitochondrial DNA release and cGAS‐STING innate immune cascade activation, and potentiates robust ...

Host‐Specific Interactions Between Staphylococcus aureus and Pseudomonas aeruginosa Impair Epithelial Repair in Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is frequently associated with polymicrobial biofilms involving Staphylococcus aureus and Pseudomonas aeruginosa. Interactions between these organisms are thought to influence disease severity, but the epithelial effects of exoproteins derived from patient‐matched cocultures remain poorly defined ...

MIT/TFE family transcription factors, Mitf and Tfec, redundantly promote pigment cell differentiation and retinal epithelium pigmentation in teleosts

Developmental Dynamics, EarlyView.
Abstract Background Transcription factors of the MIT/TFE family—mitfa, mitfb, and tfec—play essential roles in specifying pigment cells derived from neural crest cells in vertebrates. In teleosts, which possess multiple pigment cell types, these factors exhibit partially redundant but largely distinct functions across different pigment lineages.
