CC   -!- FUNCTION: Regulates expression of genes involved in acid-resistance and
CC       biofilm formation. May be a non-specific DNA-binding protein that binds
CC       genes and/or intergenic regions via a geometric recognition (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the AriR family. {ECO:0000305}.
