ABSTRACT:
The present invention relates to an isolated DNA which comprises a DNA sequence encoding avermectin aglycon synthase domains that corresponds to multifunctional enzyme proteins involved in the biosynthesis of a polyketide compound, or its mutants having avermectin aglycon synthase activity, particularly functional modules and submodules in the DNA sequence derived fromStreptomyces avermitilis, a polypeptide or mutants thereof encoded by the DNA or the mutants, a vector containing the DNA or the mutants, a host cell transformed with the DNA, the mutants thereof, or the vector, and a method for producing avermectin.
