    摘要: A method for gene shuffling to form a mutant or chimeric gene, the method comprising: (a) assigning one or more segments of one or more genes based on regions of encoded amino acid sequence; (b) amplifying the one or more assigned segments of the gene using primers specific for each segment; and (c) causing recombination of the one or more amplified segments to form a mutant or chimeric gene. An oligonucleotide primer suitable for use in gene shuffling, the primer having a non-degenerate core based on a segment or template of a gene to be amplified, and the core being flanked by both 5′ and 3′ degenerate ends.

    摘要: A method for producing a mutant gene encoding a functional gene product comprising: (a) introducing one or more mutations into a gene to form a mutated gene; (b) providing the mutated gene to a host microorganism; (c) culturing the host microorganism containing the mutated gene under conditions which allow expression of the mutant gene product; and (d) selecting a host microorganism capable of producing a functional gene production from the mutated gene.

    摘要: The invention provides a method for producing a replicase EF-Ts, EF-Tu and β polypeptide subunits, the method comprising expressing in a suitable host cell the EF-Ts and EF-Tu subunits, followed by expressing the β subunit, wherein the EF-Ts and EF-Tu subunits are operably linked to a first promoter and the β subunit is operably linked to a second promoter, and wherein the first and second promoters are differentially induced.
