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. ...

A gene cluster involved in maltodextrin transport and metabolism was identified in the genome of Lactobacillus acidophilus NCFM, which encoded a maltodextrin-binding protein, three maltodextrin ATP-binding cassette transporters and five glycosidases, all under the control of a tran-scriptional regulator of the LacI-GalR family.

The structures of isomaltase fromSaccharomyces cerevisiaeand in complex with maltose were determined at resolutions of 1.30 and 1.60 A˚ , respec-tively. Isomaltase contains three domains, namely, A, B, and C. Domain A consists of the (b⁄a)8 -barrel common to glycoside hydrolase family 13. However, the folding of domain C is rarely seen in other glycoside hydro-lase family 13 enzymes.
