'Adaptive' or 'stationary-phase' mutation is a collection of stress responses promoting mutations, some of which are advantageous. In 2000 and 2001, in Escherichia coli, adaptive gene amplification was documented, and a parallel adaptive point-mutation mechanism was linked to the error-prone DNA polymerase, DinB (pol IV). We suggest that DinB homologues may contribute to adaptive strategies of pathogens,...
Adaptive point mutation and amplification are induced responses to environmental stress, promoting genetic changes that can enhance survival. A specialized adaptive mutation mechanism has been documented in one Escherichia coli assay, but its enzymatic basis remained unclear. We report that the SOS-inducible, error-prone DNA polymerase (pol) IV, encoded by dinB, is required for adaptive point mutation...
