Xylose Metabolism Perturbation in Yarrowia lipolytica for Efficient Succinic Acid Bioproduction from Lignocellulosic Biomass

Advanced Science, EarlyView.
This study engineers Yarrowia lipolytica to produce succinic acid (SA) from lignocellulosic biomass. Adaptive evolution and multi‐omics analysis identify regulators that alleviate xylose metabolic disorder. Multi‐copy integration of xylose metabolic genes resolves redox imbalances from a futile fatty acid cycle, producing high‐titer SA from corn stover

Biomedical Applications of Nanozymes: An Enzymology Perspective

Angewandte Chemie, EarlyView.
With a lens of enzymology, this review compares nanozymes with enzymes using the Michaelis‐Menten model and differences in KM and kcat along with catalysis in complex biological environment. The implications of these differences in biomedical applications of nanozymes are then described with a statistical analysis of the trend of therapeutic use of ...

Crystallization of Adenylylsulfate Reductase from Desulfovibrio gigas: A Strategy Based on Controlled Protein Oligomerization [PDF]

, 2011
Adenylylsulfate reductase (adenosine 5′-phosphosulfate reductase, APS reductase or APSR, E.C.1.8.99.2) catalyzes the conversion of APS to sulfite in dissimilatory sulfate reduction. APSR was isolated and purified directly from massive anaerobically grown

Type 2 Diabetes‐Associated Phenylacetylglutamine Induces Deleterious Inflammation Cycle in Myeloid Cells through β2 Adrenergic Receptors and Impedes Wound Healing

Advanced Science, EarlyView.
The microbiota‐derived metabolite phenylacetylglutamine (PAGln) is elevated in type 2 diabetes and tightly associated with poor healing in both diabetic and non‐diabetic human patients. PAGln promotes mouse inflammation and impairs healing through a transmissible β2‐adrenergic receptor–mediated trained‐immunity loop.

Nanoparticle‐Modified Nanofibers Induce Ferroptosis and Stimulate Antitumor Immunity for Melanoma Therapy

Advanced Science, EarlyView.
This study presents a nanoparticle‐embedded nanofiber (5F/STFM/R‐ES) to inhibit melanoma growth and reduce the risk of metastasis and recurrence. The drug delivery system induces ferroptosis and potentiates immunotherapy through resiquimod (R848) and Fe/Mn‐based metal‐polyphenol networks (TFM).

Aluminum Exposure Impairs Electrochemically Measured Vesicular Storage and Exocytosis via Iron Homeostasis Dysregulation

Angewandte Chemie, EarlyView.
Al3+ competes with Fe3+ for transferrin (Tf) binding and enters cells via transferrin receptor (TfR)‐mediated endocytosis, disrupting cellular iron homeostasis. Intracellular vesicle impact electrochemical cytometry (IVIEC) and single‐cell amperometry (SCA), which record the oxidation of dopamine, reveal increased neurotransmitter storage and ...

Detection and characterisation of NAD(P)H-diaphorase activity in Dictyostelium discoideum cells (Protozoa)

European Journal of Histochemistry, 2012
In Dictyostelium discoideum (D. discoideum), compounds generating nitric oxide (NO) inhibit its aggregation and differentiation without altering cyclic guanosine monophosphate (cGMP) production.

Characterization of the taste receptor‐related G‐protein, α‐gustducin, in pancreatic β‐cells

Journal of Diabetes Investigation, 2020
Aims/Introduction Taste receptors, T1rs and T2rs, and the taste‐selective G‐protein, α‐gustducin, are expressed outside the taste‐sensing system, such as enteroendocrine L cells.

3',5'-Cyclic Adenosine Monophosphate- and Ca2+-Calmodulin-Dependent Endogenous Protein Phosphorylation Activity in Membranes of the Bovine Chromaffin Secretory Vesicles: Identification of Two Phosphorylated Components as Tyrosine Hydroxylase and Protein Kinase Regulatory Subunit Type II [PDF]

, 1983
: Membranes of the secretory vesicles from bovine adrenal medulla were investigated for the presence of the endogenous protein phosphorylation activity. Seven phosphoprotein bands in the molecular weight range of 250,000 to 30,000 were observed by means ...
