Specificity and topology of the Escherichia coli xanthosine permease, a representative of the NHS subfamily of the major facilitator superfamily.
Noerholm M.H., Dandanell G.
The specificity of XapB permease was compared with that of the known nucleoside transporters NupG and NupC. XapB-mediated xanthosine uptake is abolished by 2,4-dinitrophenol and exhibits saturation kinetics with an apparent K(m) of 136 microM. A 12-transmembrane-segment model was confirmed by tran ... >> More
The specificity of XapB permease was compared with that of the known nucleoside transporters NupG and NupC. XapB-mediated xanthosine uptake is abolished by 2,4-dinitrophenol and exhibits saturation kinetics with an apparent K(m) of 136 microM. A 12-transmembrane-segment model was confirmed by translational fusions to alkaline phosphatase and the alpha fragment of beta-galactosidase. << Less
