The present inventors have discovered that 3-Isopropylmalate dehydratase is essential for fungal pathogenicity. Specifically, the inhibition of 3-Isopropylmalate dehydratase gene expression in fungi results in no signs of successful infection or lesions. Thus, 3-Isopropylmalate dehydratase can be used as a target for the identification of antibiotics, preferably antifungals. Accordingly, the present invention provides methods for the identification of compounds that inhibit 3-Isopropylmalate dehydratase expression or activity. The methods of the invention are useful for the identification of antibiotics, preferably antifungals.

摘要:
The present invention relates to methods for facilitating site directed homologous recombination in a eukaryotic organism to produce genomic mutants using transposon mediated mutagenesis of cosmid vectors carrying large genomic inserts from the target eukaryotic organism. The transposon carries a bifunctional marker that can be used for selection in both bacteria and the target eukaryotic organism. Minimization of the length of the cosmid vector allows for maximization of the size of the genomic insert carried by the cosmid. Maximization of the size of the genomic insert increases the frequency of homologous recombination with the genome of the target eukaryotic organism.
摘要:
The present invention relates to a method for facilitating site directed homologous recombination in an organism to produce mutants comprising: 1) providing a large insert vector library comprising one or more large insert vectors, each of said large insert vectors comprising a piece of DNA, said DNA piece comprising multiple genes from a target organism and a first selectable marker functional for selection in bacteria; 2) providing a second vector comprising a transposable element, said transposable element comprising a nucleotide sequence coding for a second selectable marker flanked on each side by an inverted repeat sequence, wherein said selectable marker is bifunctional for selection in bacteria and the target organism and wherein said inverted repeat sequences are functional as a binding site for a transposase; 3) incubating said library with said second vector in the presence of a transposase specific for the inverted repeat sequences on the plasmid vector, such that the transposable element is transferred randomly into an individual large insert of the large insert library to produce disrupted large insert vectors; 4) optionally, amplifying the disrupted large insert vectors resulting from step 3); 5) introducing at least one of said disrupted large insert vectors into a target host cell; and 6) selecting for successful homologous recombination in said target host cell using the second selectable marker.
