title: Di-iron-tyrosyl radical ribonucleotide reductases.
abstract: New insights have been gained into the formation of the di-iron tyrosyl radical cofactor, which is essential for nucleotide reduction in the class I ribonucleotide reductases. Recent advances include Insight into the function of the tyrosyl radical in initiation of nucleotide reduction.
