Abstract excerpt
The structure of solute transporters is understood largely from analysis of their amino acid sequences, and more direct information is greatly needed. Here we report work that applies cysteine scanning mutagenesis to describe structure-function relations in UhpT, a bacterial membrane transporter. By using an impermeant SH-reactive agent to probe single-cysteine variants, we show that UhpT transmembrane segment 7...
