Ligand-induced movement of helix X in the lactose permease from Escherichia coli: a fluorescence quenching study.

Biochemistry - 18 Nov 1997

Wang Q, Matsushita K, de Foresta B, le Maire M, Kaback H R

Abstract excerpt

Five single-Trp mutants were constructed by replacing Val315, Leu318, Val326, Leu329, or Val331 with Trp in transmembrane helix X of a functional lactose permease mutant devoid of Trp residues (Trp-less permease). Taking into account expression levels, each single-Trp permease except for Val331--...
