Ribonucleotide reductases (RNR) catalyze the reduction of nucleotides to deoxynucleotides through a mechanism involving an essential cysteine based thiyl radical. In the E. coli class 1a RNR the thiyl radical (C439•) is a transient species generate

The class Ia ribonucleotide reductase (RNR) from Escherichia coli (Ec) employs a free-radical mechanism, which involves bidirectional translocation of a radical equivalent or “hole” over a distance of ∼35 Å from the stable diferric/tyrosyl-rad

Abi, A & Ferapontova, E 2012, ' Unmediated by DNA electron transfer in redox-labeled DNA duplexes end-tethered to gold electrodes ', Journal of American Chemical Society, vol. 134, no. 35, pp. 14499-14507 . https://doi.org/10.1021/ja304864w
Electron transfer (ET) between gold electrodes and redox-labeled DNA duplexes, immobilized onto the electrodes through the alkanethiol linker at the 3'-end and having internal either methylene blue (MB) or anthraquinone (AQ) redox labels, was shown t

Escherichia coli ribonucleotide reductase is an α2β2 complex that catalyzes the conversion of nucleotides to deoxynucleotides using a diferric tyrosyl radical (Y(122)(•)) cofactor in β2 to initiate catalysis in α2. Each turnover requires revers

The present study provides mechanistic details of a mild aromatic C-H activation effected by a copper(II) center ligated in a triazamacrocylic ligand, affording equimolar amounts of a CuIII-aryl species and CuIspecies as reaction products. At low tem

E. coli ribonucleotide reductase (RNR) catalyzes the conversion of nucleotides to deoxynucleotides, a process that requires long-range radical transfer over 35 A from a tyrosyl radical (Y(122)*) within the beta2 subunit to a cysteine residue (C(439))

The photocycle of bacterial photosynthetic reaction centers (RCs) involves electron transfer between two quinone molecules, QA and QB. The semiquinone biradical QA-•QB-• forms an intermediate state in this process. We trapped the biradical at low
