title: Novel mutation to dominant fucose resistance in the L-arabinose operon of Escherichia coli.
abstract: We isolated an unusual mutant in which the arabinose operon carried an araC lesion that led to a dominant fucose resistance while retaining recessive constitutivity. All previously characterized C(c) mutations have been recessive for both fucose resistance and constitutivity.
