Changing the lactose permease of Escherichia coli into a galactose-specific symporter
N-ethylmaleimide (NEM) modification of a lactose permease mutant containing a single-Cys in place of Ala-122 (helix IV) abolishes active lactose transport. Moreover, lactose, melibiose, and β,d-galactopyranosyl 1-thio-β,d-galactopyranoside protect against NEM inactivation of lactose transport and/or...
