Abstract:
:DNA sequence polymorphism was determined for the microcin V gene cluster encoded on the microcin V plasmids of 12 natural isolates of Escherichia coli. These microcin V gene clusters are similar in DNA sequence, with only 10 of the 683 bp polymorphic. Further, the levels and patterns of microcin V gene cluster polymorphism differ from those of a chromosomal region, trpORF2, sequenced from each of the host isolates. These contrasting levels and patterns of polymorphism suggest that the microcin V gene cluster has experienced an evolutionary history different from that of the host.
