ThemaltoseATP-binding cassette transporter ofSalmonella typhimurium is composed of a membrane-associated com-plex (MalFGK2) and a periplasmic receptor (MalE). In addition to its role in transport, the complex acts as a repressor ofmaltose-regulatedgene expressionand is subject to inhibition in the process of inducer exclusion. These activities are thought to be mediated by interactions of the ATPase subunit, MalK, with the transcriptional activator, MalT, and nonphosphorylated enzyme IIA of the glucose phosphotransferase system, respectively. ...
