Site-Specific Incorporation of 3-Nitrotyrosine as a Probe of pK[subscript a] Perturbation of Redox-Active Tyrosines in Ribonucleotide Reductase

E. coli ribonucleotide reductase catalyzes the reduction of nucleoside 5′-diphosphates into 2′-deoxynucleotides and is composed of two subunits: α2 and β2. During turnover, a stable tyrosyl radical (Y•) at Y[subscript 122-]β2 reversibly oxidizes C[subscript 439] in the active site of α2. This radica...
