Mechanism of maltose transport in Escherichia coli: transmembrane signaling by periplasmic binding proteins.

Proceedings of the National Academy of Sciences of the United States of America - 15 Mar 1992

Davidson A L, Shuman H A, Nikaido H

Abstract excerpt

Maltose transport across the cytoplasmic membrane of Escherichia coli is dependent on the presence of a periplasmic maltose-binding protein (MBP), the product of the malE gene. The products of the malF, malG, and malK genes form a membrane-associated complex that catalyzes the hydrolysis of ATP to provide energy for the transport event. Previously, mutants were isolated that had gained the ability to grow on...
