The BnTFL1‐BnJAM3‐BnSWEETs Module Orchestrates Seed Storage Reserve Accumulation in Brassica napus

Advanced Science, EarlyView.
BnaC03.TFL1 and BnaA01.JAM3 form a complex that facilitates the transport of soluble sugars from the seed coat to the embryo by directly activating the expression of BnSWEETs. Furthermore, BnaC03.TFL1 and BnaA01.JAM3 work cooperatively to promote soluble sugar and oil production while suppressing protein deposition.

Enhancing Enzyme Activity With Mutation Combinations Guided by Few‐Shot Learning and Causal Inference

Angewandte Chemie, EarlyView.
We present an integrated workflow that predicts activity‐enhancing mutation combinations from minimal experimental data. By proposing in vivo unit yield (yield/expression) as a surrogate for kcat/Km through causal inference, and visualizing local activity landscape, it effectively guides product yield improvement. ABSTRACT Designing enzyme sequences to

Antibacterial effects of commercially available phosphates on selected microorganisms

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
In the food industry, phosphates, polyphosphates and their salts are used, for example, as emul­si­fying agents in the production of processed cheese.

Utilization of a deoxynucleoside diphosphate substrate by HIV reverse transcriptase. [PDF]

PLoS ONE, 2008
Deoxynucleoside triphosphates (dNTPs) are the normal substrates for DNA synthesis catalyzed by polymerases such as HIV-1 reverse transcriptase (RT). However, substantial amounts of deoxynucleoside diphosphates (dNDPs) are also present in the cell. Use of

Nanozymes for Advanced Hemoglobin‐Based Oxygen Carriers: Applications in Blood Substitution, Wound Healing, Antitumor Therapy, and Beyond

Advanced Science, EarlyView.
This review explores how hemoglobin‐based oxygen carriers (HBOCs) combined with nanozymes create multifunctional materials that deliver oxygen while maintaining redox homeostasis. Beyond artificial blood substitutes, these constructs enable wound healing with light‐triggered oxygen release, cancer therapy through enhanced oxygenation and reactive ...

In vitro degradation of guanosine 5'-diphosphate, 3'-diphosphate. [PDF]

Proceedings of the National Academy of Sciences, 1977
The degradation of guanosine 5'-diphosphate,3'-diphosphate (ppGpp) by the "crude" ribosomal fraction of Escherichia coli CP78 (rel+, spoT+) was demonstrated and characterized. When the 3'-pyrophosphoryl group of ppGpp was hydrolyzed, the primary degradation product was 5'-GDP. Phosphorylation of ppGpp to guanosine 5'-triphosphate,3'-diphosphate (pppGpp)

New biocatalysts for one pot multistep enzymatic synthesis of pyrimidine nucleoside diphosphates from readily available reagents

, 2015
Since the preparation of nucleoside 5′-diphosphates by classical methodologies is complex, multistep enzymatic systems were explored to synthesize pyrimidine nucleoside 5′-diphosphates starting from readily available reagents.

Palmitic Acid Promotes Antiviral Innate Immunity via ZDHHC20‐Mediated CMPK2 Palmitoylation

Advanced Science, EarlyView.
Metabolites have important functions in innate immune activation and regulation. Wang et al. uncover metabolic regulation of antiviral immunity through CMPK2 palmitoylation, which regulates CMPK2 mitochondrial localization and is promoted by ZDHHC20 but reversed by PPT1, inhibition of which antagonizes viral infection in mice.

Synthesis of Isotopically Labelled Oligoprenyl Diphosphates and Their Application in Mechanistic Investigations of Terpene Cyclases

, 2014
A flexible, efficient and robust method for the synthesis of isotopically labelled oligoprenyl diphosphates was developed. The method makes use of just a few building blocks (acetone, triethyl phosphonoacetate, and ethyl acetoacetate) from which several ...

Leonurine Ameliorates Doxorubicin‐Induced Cardiotoxicity via STING/NF‐κB/NLRP3 Inflammasome Signaling Pathway

Advanced Science, EarlyView.
ABSTRACT Doxorubicin‐induced cardiomyopathy (DIC) remains a dose‐limiting clinical challenge. This study reveals that cardiac vascular endothelial cells (CVECs) act as initial sensors of doxorubicin cardiotoxicity: circulating doxorubicin activates the cGAS‑STING pathway in CVECs, triggering NLRP3 inflammasome‑mediated pyroptosis and release of ...
