Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

The Reaction of Creatine Kinase with 2-Chloromercuri-4-nitrophenol

Journal of Biological Chemistry, 1974
Abstract Creatine kinase from chicken breast muscle can be titrated stoichiometrically with 2 equivalents of 2-chloromercuri-4-nitrophenol, a chromophoric probe specific for thiols, without loss of enzymatic activity (Quiocho, F. A., and Thomson, J. W. (1973) Proc. Nat. Acad. Sci. U. S. A. 70, 2858–2862). The rate of reaction of mercurinitrophenol with

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Arbuscular Mycorrhizal Fungi May Account for a Phosphorus‐Facilitation Strategy

Plant, Cell &Environment, EarlyView.
ABSTRACT Mycorrhizal phosphorus (P)‐scavenging strategies are inefficient in severely P‐impoverished environments; yet many mycorrhizal species occur here. How these species acquire P and how their acquisition coordinates with root and leaf traits remain unknown.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.

Integrative SAXS and AFM analysis of engineered carbohydrate‐active enzyme assemblies with tunable spatial organization

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Cellulosomes are multi‐enzyme assemblies whose catalytic efficiency depends on the spatial organization of their components. However, their pronounced conformational flexibility has precluded quantitative characterization of inter‐enzyme distances and overall topology.
