摘要：

The antibiotic TA of Myxococcus xanthus is synthesized through a type I polyketide synthase mechanism. Previous studies have indicated that several genes essential for TA production are clustered within a 40-kb region and are transcriptionally co-regulated. In this study, we report the genetic analysis of the first gene in the TA gene cluster, identified as a NusG-like transcription anti-terminator. Functional analysis of this NusG-like anti-terminator gene by specific gene disruption confirms that it is essential for TA production bur not for normal growth and development.
