Superoxide dismutase participates in the enzymatic formation of the tyrosine radical of ribonucleotide reductase from Escherichia coli.
One of the two nonidentical subunits of Escherichia coli ribonucleotide reductase, protein B2, contains in its active form two antiferromagnetically coupled Fe(III) ions and an organic free radical that arises by the one-electron oxidation of tyrosine-122 of the polypeptide chain. Protein B2 lacking...
