Stringent alarmone, namely, guanosine 3'-diphosphate-5'-diphosphate (ppGpp), is a global regulator that plays a critical role in the survival, growth, metabolism, and many other vital processes of microorganisms. Because of its structural similarity to normal nucleotides, it is also a challenge for the selective and sensitive detection of ppGpp nowadays. Herein, we developed a colorimetric method for the selective detection of ppGpp by inhibiting the redox reaction between Fenton-like reagent… Expand
Ratiometric fluorescence detection of stringent ppGpp using Eu-MoS2 QDs test paper

Polyphosphate Functions In Vivo as an Iron Chelator and Fenton Reaction Inhibitor
PolyP, a universally conserved biomolecule, plays a hitherto unrecognized role as an iron chelator and an inhibitor of the Fenton reaction, which shows that polyP provides a crucial iron reservoir for metalloproteins under nonstress conditions and effectively chelates free iron during iron stress.

Polyphosphate Functions In Vivo as Iron Chelator and Fenton Inhibitor
It is demonstrated that polyP, a universally conserved biomolecule, plays a hitherto unrecognized role as an iron chelator and an inhibitor of the Fenton reaction, and provides a crucial iron reservoir under non-stress conditions. Expand

Highly selective detection of bacterial alarmone ppGpp with an off-on fluorescent probe of copper-mediated silver nanoclusters.
This work achieves highly selective detection of bacterial alarmone in a broad range concentration of 2-200 μM, but also improves the understanding of the specific recognitions among DNA-Ag NCs, Cu(2+), and ppGpp. Expand
A radioimmunoassay for (p)ppGpp and its application to Streptomyces hygroscopicus
The very sensitive radioimmunoassay allowed determination of very low amounts: 1–50 pmoles (p)ppGpp per assay tube and the application of the RIA to S. hygroscopicus revealed a basal level in exponentially growing mycelium of about 2 pmoles. Expand
Novel findings on the copper catalysed oxidation of cysteine
SummaryThe oxidation of cysteine (RSH) has been studied by using O2, ferricytochrome c (Cyt c) and nitro blue tetrazolium (NBT) as electron acceptors. The addition of 200μM CuII to a solution of 2mMExpand
The Fenton reagents.
The question whether free .OH radicals are being formed or not via the Fenton reaction depends on the relative rates of the decomposition reactions of the metal-peroxide complex and that of its reaction with organic substrates. Expand
