While many 3D structures of cation-coupled transporters have been determined, the mechanistic details governing the obligatory coupling and functional regulations still remain elusive. The bacterial melibiose transporter (MelB) is a prototype of majo

The structure of lactose permease, stabilized in a periplasmic open conformation by two Gly to Trp replacements (LacYww) and complexed with a nanobody directed against this conformation, provides the highest resolution structure of the symporter. The

Bacterial sugar symporters in the Major Facilitator Superfamily (MFS) use the H+ (and in a few cases Na+) electrochemical gradients to achieve active transport of sugar into the cell. Because a number of structures of MFS sugar symporters have been s

Significance Protonation and deprotonation of Glu325 with a pKa of 10.5 is required for symport. Moreover, the H+ electrochemical gradient (∆μ∼H+) accelerates deprotonation on the intracellular side with a 50- to 100-fold decrease in the Km. To

Bacterial transporters are difficult to study using conventional electrophysiology because of their low transport rates and the small size of bacterial cells. Here, we applied solid-supported membrane–based electrophysiology to derive kinetic param

Significance The alkaline pK for galactoside binding by the lactose permease of Escherichia coli correlates precisely with the pK a of Glu325, as determined by reaction-induced surface-enhanced infrared absorption spectroscopy (SEIRAS). Glu325 must b
