RESUMO
A new uvrA mutation (uvrA276) has been isolated on a multicopy plasmid and shown to reside within the region of the uvrA gene defined by the KpnI to SalI endonuclease sites. The protein produced by the uvrA276 mutant gene is identical in size to the wild-type protein and binds to single-stranded DNA under the same conditions as the wild-type protein. However, extracts prepared from strains containing this mutant are deficient at incision of DNA that has been irradiated with UV light.
