Trp replacements for tightly interacting Gly–Gly pairs in LacY stabilize an outward-facing conformation

Trp replacements for conserved Gly–Gly pairs between the N- and C-terminal six-helix bundles on the periplasmic side of lactose permease (LacY) cause complete loss of transport activity with little or no effect on sugar binding. Moreover, the detergent-solubilized mutants exhibit much greater therma...
