The pcnB gene of Escherichia coli, which is required for ColE1 copy number maintenance, is dispensable.

Journal of bacteriology - 1 Jul 1993

Abstract excerpt

The pcnB gene product of Escherchia coli is required for copy number maintenance of plasmids related to ColE1 and also for that of the IncFII plasmid R1. Because PcnB is similar to the tRNA-binding protein tRNA nucleotidyltransferase, we have suggested that the protein would be required only for...
