CLONAGEM DA VIA DE BIOSSINTESE PARA FORMACAO DE CLORTETRACICLINA E TETRACICLINA A PARTIR DE STREPTOMYCES AUREOFACIENS E SUA EXPRESSAO EM STREPTOMYCES LIVIDANS

The present invention relates to the cloning, isolation and DNA (isolated fragment from Streptomyces aureofaciens) which directs the synthesis of tetracycline and chlortetracycline, in a heterologous host such as Streptomyces lividans. The claimed plasmids are isolated by screening a cosmid library,...

Beschreibung
Zusammenfassung:	The present invention relates to the cloning, isolation and DNA (isolated fragment from Streptomyces aureofaciens) which directs the synthesis of tetracycline and chlortetracycline, in a heterologous host such as Streptomyces lividans. The claimed plasmids are isolated by screening a cosmid library, constructed in Escherichia coli, for the expression of tetracycline resistance in S. lividans.
