WitrynaThe MarR family transcriptional regulators are known to be repressors of genes activating the oxidative stress regulons. OhrR is a transcriptional repressor of the organic hydroperoxide resistance protein (OhrA). The gene ohrR deficient mutant revealed a strong resistance to H 2 O 2 in L. casei IGM394 . OhrA was not detected in this study.
