Identification
Name:Sugar efflux transporter
Synonyms:Not Available
Gene Name:sotB
Enzyme Class:Not Available
Biological Properties
General Function:Involved in transmembrane transport
Specific Function:Involved in the efflux of sugars. The physiological role may be the reduction of the intracellular concentration of toxic sugars or sugar metabolites. Transports L-arabinose and to a lesser extent IPTG. Seems to contribute to the control of the arabinose regulon
Cellular Location:Cell inner membrane; Multi-pass membrane protein
