13. Transcriptional analysis of the Streptomyces glaucescens tetracenomycin C biosynthesis gene cluster.
A 12.6-kb DNA fragment from Streptomyces glaucescens GLA.0 containing the 12 genes for tetracenomycin (TCM) C biosynthesis and resistance enabled Streptomyces lividans to produce TCM C. Transcriptional analysis of the tcmPG intergenic region in this cluster established the presence of two divergent promoters. The tcmIc mutation, a T-to-G transversion in the

14. Rapid site-specific DNA inversion in Escherichia coli mutants lacking the histonelike protein H-NS.
Escherichia coli pilG mutants are thought to have a dramatically higher DNA inversion rate as measured by the site-specific DNA inversion of the type 1 pili pilA promoter. DNA sequence of the pilG gene confirmed its identity to the gene encoding the bacterial histonelike protein H-NS. Unlike other histonelike protein complexes that enhance site-specific DNA
