Complete nucleotide sequence of the Hsd plasmid pECO29 and identification of its functional regions.
The complete nucleotide sequence of the Hsd plasmid pECO29 has been determined. The plasmid DNA consists of 3895 base pairs. These include 4 genes and 5 sites. Two genes encoding the proteins (restriction endonuclease and DNA methyltransferase) have been fully characterized. The pECO29 comprises a Co1El-type replication system coding for untranslated genes RNAI and RNAII, the emr recombination site containing palindromic sequences and involved in stable maintenance of the plasmid, two pseudo oriT sites homologous to the oriT site of R64 and F plasmids, as well as the bom locus of a Co1El-like plasmid. There are no genes involved in the mobilization of pECO29 plasmid.
