Physiological evidence for an interaction between helix XI and helices I, II, and V in the melibiose carrier of Escherichia coli.

Biochemical and biophysical research communications - 16 Feb 2000

Ding P Z, Wilson T H

Abstract excerpt

In a previous study 23 residues in helix XI of the cysteine-less melibiose carrier were changed individually to cysteine. Several of these cysteine mutants (K377C, A383C, F385C, L391C, G395C) had low transport activity and they were white on melibiose MacConkey fermentation plates. After several days of incubation of these white clones on melibiose MacConkey plates a rare red mutant appeared. The plasmid DNA was...
