Zusammenfassung: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. Ovaj pronalazak se odnosi na polinukleotidne molekule koji sadrže nukleotidne sekvence koje kodiraju produkt aveC gena, gde ti polinukelotidni molekuli mogu biti korišćeni da izmene odnos ili količinu klase 2:1 avermektina proizvedenih u fermentacionim kulturama S. avermitilis Ovaj pronalazak se dalje odnosi na vektore, ćelije domaćine, i mutante sojeve S. avermitilis u kojima je aveC gen inaktiviran, ili mutiran tako da menja odnos ili količinu klase 2:1 proizvedenih avermektina.[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.
