Error-prone DNA polymerase IV is controlled by the stress-response sigma factor, RpoS, in Escherichia coli.

Molecular microbiology - 1 Oct 2003

Layton Jill C, Foster Patricia L

Abstract excerpt

An insertion in rpoS, which encodes the general stress response sigma factor sigma 38, was isolated as an antimutator for 'stationary-phase' or 'adaptive' mutation. In the rpoS mutant strain the levels of error-prone DNA polymerase Pol IV were reduced. Pol IV is encoded by the dinB gene, and the amount of its transcript was also reduced in rpoS mutant cells. In wild-type cells, the levels of Pol IV increased in...
