GENE, DIE VERZWEIGTE-ALPHA-KETOSÄURE- DEHYDROGENASEKOMPLEXE VON STREPTOMYCES AVERMITIUS KODIEREN

摘要

The present invention relates to novel DNA sequences that encode for the branched-chain alpha-ketoacid dehydrogenase complex of an organism belonging to the genus Streptomyces and to novel polypeptides produced by the expression of such sequences. It also relates to novel methods of enhancing the production of natural avermectin and of producing novel avermectin through fermentation.
