The proton electrochemical gradient induces a kinetic asymmetry in the symport cycle of LacY
LacY catalyzes accumulation of galactosides against a concentration gradient by coupling galactoside and H(+) transport (i.e., symport). While alternating access of sugar- and H(+)-binding sites to either side of the membrane is driven by binding and dissociation of sugar, the electrochemical H(+) g...
