High-field EPR detection of a disulfide radical anion in the reduction of cytidine 5′-diphosphate by the E441Q R1 mutant of Escherichia coli ribonucleotide reductase
Class I ribonucleotide reductases (RNRs) are composed of two subunits, R1 and R2. The R2 subunit contains the essential diferric cluster–tyrosyl radical (Y⋅) cofactor and R1 is the site of the conversion of nucleoside diphosphates to 2′-deoxynucleoside diphosphates. A mutant in the R1 subunit of Esc...
