The Escherichia coli histone-like protein HU has a role in stationary phase adaptive mutation.

Abstract excerpt

Stationary phase adaptive mutation in Escherichia coli is thought to be a mechanism by which mutation rates are increased during stressful conditions, increasing the possibility that fitness-enhancing mutations arise. Here we present data showing that the histone-like protein, HU, has a role in the molecular pathway by which adaptive Lac(+) mutants arise in E. coli strain FC40. Adaptive Lac(+) mutations are...
