Novel Mutation to Dominant Fucose Resistance in the l-Arabinose Operon of Escherichia coli1

AUTOR(ES)
RESUMO

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 Cc mutations have been recessive for both fucose resistance and constitutivity.
