Resumo: Ribonucleotide reductase catalyses the de novo synthesis of deoxyribonucleotides. Class I reductases use an iron center to generate a tyrosyl free radical that can initiate formation of the deoxyribonucleotide. These reductases are alpha 2 beta 2 holoenzymes, and the subunits are denoted as R1 and R2. R1 contains the allosteric binding site and the active site, whereas R2 contains a binuclear iron center that initiates formation of the tyrosyl radical. We have cloned and sequenced the cDNAs encoding the R1 and R2 subunit in the yellow fever mosquito, Aedes aegypti. The messages for these proteins are increased in response to blood-feeding.
