Molecular Genetics of Red Biosynthesis in Streptomyces

Abstract
We have studied the molecular biology of undecylprodigiosin (Red) biosynthesis by Streptomyces coelicolor as a model system for understanding the genetic regulation of antibiotic biosynthesis. A collection of new red mutants was obtained using a directed screen. Regions of DNA involved in the transcriptional regulation of red gene expression were also isolated.
