Engineered Biocatalyst for Enantioselective Hydrazone Reduction

Angewandte Chemie, EarlyView.
Here, we report the discovery and engineering of a hydrazone reductase (HRED) biocatalyst that promotes efficient reduction of protected hydrazones with exceptional stereocontrol. These biotransformations offer a sustainable strategy for synthesizing valuable chiral N─N containing products that are commonly found in pharmaceuticals and agrochemicals ...

Identifying Novel Inhibitors of RpFabG in Typhus-inducing Rickettsia prowazekii [PDF]

, 2019
Epidemic typhus is a rickettsial disease that is contracted via ticks and lice found on the flying squirrel. The disease is caused by Rickettsia prowazekii, an intracellular, gram-negative coccobacillus.

Lipid Droplet‐Organized MDM2‐Mediated P53 Degradation: A Metabolic Switch Governing Diet‐Driven Tumor Progression

Advanced Science, EarlyView.
Tumor‐associated TP53 inactivation correlates with lipid droplet (LD) accumulation. High‐fat diets drive Cyb5r3‐Myh9‐mediated p53 enrichment on LD surfaces, accelerating its degradation while upregulating LD‐promoting factor CD36 expression to establish a feed‐forward loop. LD suppression or dietary intervention restores p53 and inhibits tumorigenesis,

Sites of Biosynthesis of Outer and Inner Membrane Proteins of Neurospora crassa Mitochondria [PDF]

, 1970
Outer and inner membranes of Neurospora crassa mitochondria were separated by the combined swelling, shrinking, sonication procedure. Membranes were characterized by electron microscopy and by marker enzyme activities.

High‐Throughput Tiling of Essential mRNAs Increases Potency of Antisense Antibiotics

Advanced Science, EarlyView.
The systematic tiling of essential genes’ mRNA here presented, proposes a valuable tool for the identification of novel PNA sequences with antibiotic potential. The high‐throughput synthetic set up opens the door to investigating thousands of sequences in an economic way and ultimately identifies potent antisense oligonucleotides while also giving room

An Artificial Metal‐Free Peroxidase Designed Using a Ferritin Cage for Bioinspired Catalysis

Angewandte Chemie, EarlyView.
Designing artificial enzymes remains challenging due to the need for precise active site control. Here, we present a simple strategy to create metal‐free artificial enzymes by engineering Histidine clusters inside a ferritin cage. The resulting catalyst mimics peroxidase activity, and its stable cage structure offers new insights into supramolecular ...

Single‐Cell Transcriptome Reveals Aquaporin‐Mediated Carbon Nanosol‐Induced Growth Promotion of Plants

Advanced Science, EarlyView.
Carbon nanosol (CNS) exhibits rapid root penetration capacity, enhancing plant growth through boosting stomatal density and antioxidative enzyme activity. Single‐cell transcriptomic profiling uncovers cell type‐specific gene expression patterns and developmental trajectories during CNS‐mediated growth promotion.

circNR3C2 promotes chondrogenic differentiation and cartilage repair of human adipose‐derived stem cells via the hsa‐miR‐647/SOX9 pathway

Animal Models and Experimental Medicine, EarlyView.
The hypothesis diagram illustrates the function and mechanism of circNR3C2: circNR3C2 overexpression can up‐regulate COL2, Aggrecan and SOX9 expression, and regulate chondrogenic differentiation of hADSCs by targeting hsa‐miR‐647. Abstract Background Human adipose‐derived stem cells (hADSCs) are seed cells with application prospects in cartilage repair.
