RT   involved in the catabolism of aromatic compounds in Bacillus subtilis.";
RL   Proteomics 7:1391-1408(2007).
CC   -!- FUNCTION: Putative oxidoreductase that may contribute to the
CC       degradation of aromatic compounds. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- INDUCTION: Repressed by MhqR. Strongly induced by stress due to
CC       exposure to 2-methylhydroquinone (2-MHQ) and less strongly induced
CC       after diamide or catechol stress. Not induced by oxidative stress due
CC       to hydrogen peroxide or methylglyoxal. {ECO:0000269|PubMed:17407181,
CC       ECO:0000269|PubMed:17725564}.
CC   -!- SIMILARITY: Belongs to the DoxX family. {ECO:0000305}.
