Mutations in the trfA replication gene of the broad-host-range plasmid RK2 result in elevated plasmid copy numbers.

Mutated forms of trfA, the replication protein gene of plasmid RK2, that support a minimal RK2 origin plasmid in Escherichia coli at copy numbers up to 23-fold higher than normal have been isolated. Six such high-copy-number (copy-up) mutations were mapped and sequenced. In each case, a single base...
