title: Analysis of a 1.6-micron circular plasmid from the yeast Kluyveromyces drosophilarum: structure and molecular dimorphism.
abstract: A new plasmid has been found in the yeast Kluyveromyces drosophilarum. It is a double-stranded circular DNA, 1.6 micron in length (4.8 kilobase pairs). As in the case of Saccharomyces 2 mu circles, this plasmid occurs in two isomeric forms corresponding to the inversion of a segment between two 346-bp-long inverted repeats within the molecule. Each form has been separately cloned into bacterial plasmids. The new yeast plasmid, called pKD1, contains sequences that allow its replication in Saccharomyces cerevisiae.
