  • Polymyxin synthetase and gene cluster thereof
    Patent number: 8329430
    Abstract: The present invention relates to a polymyxin synthetase isolated from Gram-positive Paenibacillus sp. and a gene cluster encoding the same, more precisely a polymyxin synthetase isolated from Paenibacillus polymyxa E681, ATCC21830 and F4 strains, a gene cluster encoding thereof and a preparation method of polymyxin or its derivatives using the gene cluster. The polymyxin synthetase of the present invention can be effectively used for the increase of productivity of polymyxin and the development of a novel antibiotic.
    Type: Grant
