Fig. 1From: Using in vivo oxidation status of one- and two-component redox relays to determine H2O2 levels linked to signaling and toxicityScheme depicting the two types of H2O2-sensing modules: the one-component OxyR and the two-component Tpx1-Pap1 systems. Some of the genes regulated by these systems are indicated. See text for details. E. coli Escherichia coli, S. pombe Schizosaccharomyces pombeBack to article page
