Mutagenic DNA repair in Escherichia coli. XVIII. Involvement of DNA polymerase III alpha-subunit (DnaE protein) in mutagenesis after exposure to UV light.

Mutagenesis - 1 Jan 1990

Bridges B A, Bates H

Abstract excerpt

UV light was unable to induce rifampicin-resistant mutations at 43 degrees C in Escherichia coli ER11 dnaE486. Although DnaE486 gene product is inactive at 43 degrees C, these bacteria contain the pcbA1 mutation which allows DNA replication provided DNA polymerase I is functional. The experiments were carried out under conditions where full expression of rifampicin-resistant mutations could occur so that the lack...
