CC   -!- FUNCTION: Regulator of exopolysaccharide synthesis. Represses the
CC       activation of EPS II (exp) genes for galactoglucan and activates the
CC       EPS I (exo) genes for succinoglycan. Also negatively regulates its own
CC       transcription.
CC   -!- SIMILARITY: Belongs to the ros/MucR family. {ECO:0000305}.
