pubmed:abstractText |
Recombinant plasmids containing all or part of the genetic region of Escherichia coli coding for the two subunits of ribonucleoside diphosphate reductase (proteins B1 and B2) were constructed with the aid of the multicopy plasmid pBR322. Two of these plasmids (pPS1 and pPS2) appeared to carry both a regulator and the complete structural information for the enzyme and, after transformation of E. coli, directed a 10- to 20-fold overproduction of both proteins B1 and B2. The other plasmids (pPS101 and pPS201) carried structural information for only protein B2. Cells carrying pPS1 and pPS2 showed a 5- to 500-fold increased resistance against the drug hydroxyurea. This establishes that in E. coli the inhibition of deoxyribonucleic acid synthesis by hydroxyurea is fully explained by its action on ribonucleotide reductase.
