The Active Form of the Saccharomyces cerevisiae Ribonucleotide Reductase Small Subunit Is a Heterodimer in Vitro and in Vivo()

The class I ribonucleotide reductases (RNRs) are composed of two homodimeric subunits: R1 and R2. R2 houses a diferric-tyrosyl radical (Y•) cofactor. Saccharomyces cerevisiae has two R2s: Y2 (β(2)) and Y4 (β′(2)). Y4 is an unusual R2 because three residues required for iron binding have been mutated...
