Abstract

pKD1 is the only circular plasmid known in the genus Kluyveromyces. Nucleotide sequence analysis has revealed that this 4757 base-pairs long plasmid contained three major open reading frames, A, B, and C, and a pair of inverted repeats of 346 base-pairs. The molecule exists in two isomeric forms generated by internal recombination at these repeats. The functional organization of pKD1 genome appears to be quite analogous to that of the 2u plasmid of Saccharomyces cerevisiae. There is however little homology of sequences between these plasmids, except that the gene A has a dispersed but significant homology with the FLP recombinase gene of the 2u plasmid. S.cerevisiae cells can be transformed by derivatives of pKD1 carrying URA3 gene as a selection marker.
