  • Title: [Replication in yeasts of plasmid pE194 from Staphylococcus aureus].
    Author: Polumienko AL, Grigor'eva SP.
    Journal: Mol Biol (Mosk); 1986; 20(1):219-23. PubMed ID: 3005842.
    Abstract:
    The ability of the plasmid pE194 from S. aureus to serve as an autonomously replicating sequence (ARS) in yeast was shown. The hybrid plasmid pLD744 that contains pE194 and the yeast LEU2 gene sequences is unstable in yeast like other YRp-vectors: the mitotic stability of the pLD744 was as much as 1%. The plasmid pLD712 that differs from pLD744 by the existence of a centromeric sequence from the chromosome III of yeast Saccharomyces cerevisiae reveals about one order greater stability. The observation that there are some sequences in the primary structure of the pE194 which strongly conform to the ARS consensus in yeast inclines us to infer that the existence of ARS consensus on pE194 DNA is not sufficient for its effective replication in yeast.
