Abstract excerpt

Each of the two beta peptides which comprise the B2 protein of Escherichia coli ribonucleotide reductase (RRB2) possesses a nonheme dinuclear iron cluster and a tyrosine residue at position 122. The oxidized form of the protein contains all high spin ferric iron and 1.0-1.4 tyrosyl radicals per R...
