Substrate specificity and transport properties of the glycerol facilitator of Escherichia coli.
The specificity of the glycerol facilitator (glpF) of Escherichia coli was studied with an osmotic method. This transport system allowed the entry of polyols (glycerol and erythritol), pentitols, andExpand

The role of energy coupling in the transport of beta-galactosides by Escherichia coli.
Abstract Lactose and o-nitrophenylgalactoside (NPG) were transported against considerable concentration gradients by ML 308-225, a mutant of Escherichia coli which lacks β-galactosidase but possessesExpand
