RL   J. Bacteriol. 181:426-433(1999).
CC   -!- FUNCTION: Transcriptional repressor for the exu locus which is required
CC       for galacturonate utilization. {ECO:0000305}.
CC   -!- INDUCTION: Induced by galacturonate, repressed by glucose.
CC       {ECO:0000305|PubMed:9882655}.
CC   -!- DISRUPTION PHENOTYPE: Cells lacking this gene express the exu locus
CC       genes (required for hexuronate utilization) constitutively. Its absence
CC       additionally confers the ability to grow on minimal medium plus
CC       glucuronate, which cells cannot do in the presence of ExuR.
CC       {ECO:0000269|PubMed:9882655}.
