Construction of mini-F plasmid vectors for plasmid shuffling in Escherichia coli

We have constructed two Escherichia coli mini-F plasmid vectors, pJK286 and pJK289, which have unique EcoRI, BamHI and HindIII sites downstream from the lac promoter. The mini-F vectors are useful for plasmid shuffling, with which we can efficiently carry out localized mutagenesis.
