Adaptation to oxidative stress is a major topic in basic and applied research. Cell response to stressful changes is realized through coordinated reorganization of gene expression. E. coli and S. cerevisiae are extremely amenable to genetic or molecular biological and biochemical approaches, which make these microorganisms suitable models to study stress response at a molecular level in prokaryotes and eukaryotes, respectively. The main focus of this review is (i) to discuss transcriptional control of global response to hydrogen peroxide in E. coli and S. cerevisiae, (ii) to summarize recent literature data on E. coli and S. cerevisiae adaptive response to oxidative stress at different stages of the flow of the genetic information: from transcription and translation to functionally active proteins and (iii) to discuss possible reasons for a lack of correlation between the expression of certain antioxidant genes at different levels of cellular organization.
