    摘要: The present invention relates to combinatorial gene expression libraries and methods for making these. Such libraries are useful in discovery of novel and/or enhanced metabolic pathways leading to the production of novel compounds for e.g drug discovery and/or to the production of known compounds in novel quantities or in novel compartments of the cells. The expression libraries in particular are composed of host cells capable of co-ordinated and controllable expression of large numbers of heterologous genes in the host cells.

    摘要: The present invention relates to methods of mixing large numbers of heterologous genes, which are located on artificial chromsomes. The methods of the present invention are useful for evolution of cells and whole genomes to acquire new functionality(ies), such as the ability to synthesise novel secondary metabolites and/or the evolution of novel metabolic pathways. In particular the methods may involve mating or fusing two populations of cells, each population comprising different combinations of heterologous genes. Subsequently, desirable cells may be selected. In embodiments of the invention the heterologous genes are comprised within expression cassettes. The expression cassette can be in the form of a concatermer, and can be cut out using a restriction enzyme in order to make new combinations of expression cassettes.

    摘要: In the present invention are disclosed concatemers of concatenated expression cassettes and vectors that enable the synthesis of such concatemers. The concatemer comprises in the 5′→3′ direction a cassette of nucleotide sequence of the general formula [rs2-SP-PR-X-TR-SP-rs1]n wherein rs1 and rs2 together denote a functional restriction site, SP individually denotes a spacer of at least two nucleotide bases, PR denotes a promoter, capable of functioning in a cell, X denotes an expressible nucleotide sequence, TR denotes a terminator, and SP individually denotes a spacer of at least two nucleotide bases, and n>/=2, and wherein at least a first cassette is different from a second cassette. The main purpose of these concatemers is the controllable and co-ordinated expression of large numbers of heterologous genes in a single host. Furthermore, the invention relates to a concatemer of cassettes of nucleotide sequences and a method for preparing the concatemers. In a further aspect, the invention relates to transgenic host cells comprising at least one concatemer according to the invention, as well as to a method for preparing the transgenic host cells. Finally, the invention relates to a vector comprising a cassette of nucleotides, a method for preparing said vector, a nucleotide library comprising at least two primary vectors each comprising a cassette of nucleotides, a method for preparing the library.
