Abstract
The present invention relates to cloned DNA containing origin of DNA replication and to cloned DNA encoding repliation protein, RepT.
Claims1
A method for cloning Thermus sp. plasmid genes comprising the steps of:
- (a) isolating plasmid DNA from Thermus sp. cells wherein the plasmid comprises at least one Thermus sp. origin of replication;
- (b) inserting said plasmid DNA into a recombinant plasmid comprising a thermostable kanarnycin-resistance gene and an E. coli replication origin to produce a cloned recombinant plasmid;
- (c) transforming an E. coli sp. host cell with the cloned recombinant plasmid of step (b) and culturing said E. coli sp. host cell for the expression of said cloned recombinant plasmid;
- (d) isolating the cloned recombinant plasmid from said cell;
- and
- (e) transforming a Thermus sp. host cell with said cloned recombinant plasmid from step (d) and culturing said Thermus sp. host cell.
