The melibiose carrier of Escherichia coli: cysteine substitutions for individual residues in helix XI.

The Journal of membrane biology - 15 Mar 2000

Ding P Z, Wilson T H

Abstract excerpt

The melibiose carrier from Escherichia coli is a sugar-cation cotransport system. Previously evidence was obtained that this integral membrane protein consists of 12 transmembrane helices. Starting with the cysteine-less melibiose carrier, cysteine has been substituted individually for amino acids 374-396, which includes all of the residues in the proposed helix XI. The carriers with cysteine substitutions were...
