    摘要: A bioactive compound, or family of compounds, is biosynthesised by a cell using a plurality of enzymic activities. Host cells are provided that substantially lack the bioactivity, but possess at least a first one of the enzymic activities (or nucleic acid encoding a corresponding enzyme). The cells are transformed with nucleic acid expressible to provide at least a second enzymic activity which enables the cells to produce a bioactive compound. A family of cells may be transformed with a multiplicity of different nucleic acids, leading to a library of cells including cells producing different bioactive product, and cells not producing bioactive products. Transformed cells may be screened for bioactivity. Active cells may be isolated and cultured, and bioactive compounds may be isolated.

    摘要: The present invention relates to polynucleotide molecules comprising nucleotide sequences encoding an aveC gene product, which polynucleotide molecules can be used to alter the ratio or amount of class 2:1 avermectins produced in fermentation cultures of S. avermitilis. The present invention further relates to vectors, host cells, and mutant strains of S. avermitilis in which the aveC gene has been inactivated, or mutated so as to change the ratio or amount of class 2:1 avermectins produced.
