Engineering ascorbic acid biosynthetic pathway in Arabidopsis leaves by single and double gene transformation

Biologia Plantarum, 2012
Six genes, which encode enzymes involved in ascorbic acid (AsA) biosynthesis, including guanosine diphosphate (GDP)-mannose pyrophosphorylase (GMP), GDP-mannose-3',5'-epimerase (GME), GDP-galactose guanylyltransferase (GGT), L-galactose-1-phosphate ...

Stringent control of RNA synthesis in the absence of guanosine 5‘-diphosphate-3‘-diphosphate.

Journal of Biological Chemistry, 1981
Severe curtailment of RNA synthesis and widespread readjustment of cellular activities, together with an increase of guanosine 5'-diphosphate-3'-diphosphate (ppGpp) have been demonstrated in Escherichia coli cells starved for amino acid or energy. The rates of growth and RNA synthesis are reduced by shifting the growth temperature from 40 degrees C to ...

Thermodynamic characterisation of covalent ligand binding

British Journal of Pharmacology, EarlyView.
Background and Purpose Differential scanning fluorimetry (DSF) is a common and straightforward method to evaluate the thermal stability of proteins and has been heavily used for ligand binding characterisation as well as for screening. One class of compounds that is less typically evaluated by DSF are covalent binders.

Daraxonrasib and Beyond: Pan‐RAS Inhibition, Resistance, and Next‐Generation Strategies

Cancer Science, EarlyView.
ABSTRACT RAS proteins have long been considered difficult therapeutic targets, but allele‐selective inhibitors established the clinical tractability of mutant RAS. Daraxonrasib (RMC‐6236), an oral pan‐RAS inhibitor, has now extended this concept by targeting multiple mutant and wild‐type RAS proteins.

Profile of Nucleotides and Nucleosides in Taiwanese Human Milk

Pediatrics and Neonatology, 2011
Human milk–borne nucleotides and their related metabolic products have been reported to have important physiological roles in breast-fed infants. The purpose of this study was to measure the concentrations of free nucleotides and nucleosides in human ...

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

The FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Homology Modeling of Human Uridine-5′-diphosphate-glucuronosyltransferase 1A6 Reveals Insights into Factors Influencing Substrate and Cosubstrate Binding

, 2020
The elimination of numerous endogenous compounds and xenobiotics via glucuronidation by uridine-5′-diphosphate glycosyltransferase enzymes (UGTs) is an essential process of the body’s chemical defense system.

Periodontal Medicine Rewired: Mechanisms Linking Periodontitis to Systemic Diseases

Journal of Periodontal Research, EarlyView.
This review reorganizes decades of research in periodontal medicine into a multi‐dimensional framework, illustrating how periodontitis influences systemic health through at least seven interconnected mechanisms. ABSTRACT Periodontitis is now recognized not merely as a localized oral condition but as a systemic disease linked to over 70 communicable and

Activation of Escherichia coli phosphoenolpyruvate carboxylase by guanosine‐5′‐diphosphate‐3′‐diphosphate

FEBS Letters, 1977
Bacteria such as Escherichia coli respond to amino acid starvation by reducing the rate of syntheses of RNA, lipids, nucleotides and glycolytic esters [1,2]. This phenomenon is termed ‘stringent response’. It has been pointed out that, concomitant with this cellular response, a sharp increase in the intracellular levels of guanosine$-diphosphate3 ...

A multi‐omics investigation of sarcopenia and frailty: Integrating genomic, epigenomic and telomere length data

Experimental Physiology, EarlyView.
Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty. In this
