Truncation of MalF results in lactose transport via the maltose transport system of Escherichia coli.

The Journal of biological chemistry - 23 Jan 1998

Merino G, Shuman H A

Abstract excerpt

The active accumulation of maltose and maltodextrins by Escherichia coli is dependent on the maltose transport system. Several lines of evidence suggest that the substrate specificity of the system is not only determined by the periplasmic maltose-binding protein but that a further level of subst...
