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

Summary Respiratory complex I drives proton translocation across energy-transducing membranes by NADH oxidation coupled with (ubi)quinone reduction. In humans, its dysfunction is associated with neurodegenerative diseases. The Escherichia coli comple
