Genetic analysis of periplasmic binding protein dependent transport in Escherichia coli. Each lobe of maltose-binding protein interacts with a different subunit of the MalFGK2 membrane transport complex.

Abstract excerpt

Escherichia coli is able to accumulate maltose and maltodextrins by an ATP-binding cassette transporter known as the maltose transport system. This transport system is comprised of five proteins: the LamB protein in the outer membrane; the periplasmic maltose-binding protein (MBP); two integral inner membrane proteins, MalF and MalG; and MalK, which is associated with the cytoplasmic face of the inner membrane....
