Alteration in cation specificity of the melibiose transport carrier of Escherichia coli due to replacement of proline 122 with serine.
The structural genes (melB) for the melibiose carrier of five mutants of Escherichia coli showing altered cation specificity for melibiose transport were cloned. The mutations were mapped in a 248-base-pair DNA fragment by a recombinational assay by using the mutants transformed with hybrid plasmids...
