Vectors for the cloning and expression of heterologous genes in yeast and the yeast strains transformed by said vectors

摘要

Vectors for the cloning and expression of heterologous genes in yeast, said vectors being characteristic in that they contain at least: the entire DNA of the pkD1 plasmid (isolated from Kluyveromyces drosophilarum) or a part of the same, as well as a DNA segment bearing any heterologous gene and the sequence necessary for the expression of said gene. The high stability of yeasts transformed by said vectors allows their utilization on an industrial scale in various biotechnological fields.
