abstractText  We have isolated and sequenced overlapping cDNA clones containing the entire coding region of mouse ribonucleotide reductase subunit M1. The coding region comprises 2.4 kilobases and predicts a polypeptide of 792 amino acids (Mr 90,234) which shows striking homology with ribonucleotide reductases from Escherichia coli and the herpesviruses, Epstein-Barr virus and herpes simplex virus. The homologies reveal three domains: an N-terminal domain common to the mammalian and bacterial enzymes, a C-terminal domain common to the mammalian and viral ribonucleotide reductases, and a central domain common to all three. We speculate on the functional basis of this conservation.
