RT   "Characterization of SotA and SotB, two Erwinia chrysanthemi proteins which
RT   modify isopropyl-beta-D-thiogalactopyranoside and lactose induction of the
RT   Escherichia coli lac promoter.";
RL   J. Bacteriol. 182:1340-1345(2000).
CC   -!- FUNCTION: Involved in the efflux of sugars. The physiological role may
CC       be the reduction of the intracellular concentration of toxic sugars or
CC       sugar metabolites. Transports IPTG, lactose and melibiose.
CC       {ECO:0000269|PubMed:10671456}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane
CC       {ECO:0000305|PubMed:10671456}; Multi-pass membrane protein
CC       {ECO:0000305|PubMed:10671456}.
CC   -!- INDUCTION: Activated by glucose, and to a lesser extent by other
CC       metabolizable sugars such as galacturonate, arabinose and melibiose.
CC       Repressed by cyclic AMP receptor protein (CRP).
CC       {ECO:0000269|PubMed:10671456}.
CC   -!- SIMILARITY: Belongs to the major facilitator superfamily. SotB (TC
CC       2.A.1.2) family. {ECO:0000305}.
