CC -!- FUNCTION: Activates the transcription of the soxS gene which itself
CC controls the superoxide response regulon. SoxR contains a 2Fe-2S iron-
CC sulfur cluster that may act as a redox sensor system that recognizes
CC superoxide. The variable redox state of the Fe-S cluster is employed in
CC vivo to modulate the transcriptional activity of SoxR in response to
CC specific types of oxidative stress (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
