    The specificity of ribonucleotide reductases (RNRs) toward their four substrates is governed by the binding of deoxyribonucleoside triphosphates (dNTPs) to the allosteric specificity site. Similar patterns in the kinetics of allosteric regulation have been a strong argument for a common evolutionary origin of the three otherwise widely divergent RNR classes. Recent structural information settled the case for divergent evolution; however, the structural basis for transmission of the allosteric signal is currently poorly understood. A comparative study of the conformational effects of the binding of different effectors has not yet been possible; in addition, only one RNR class has been studied.
