A simple and high-throughput transposon mediated mutagenesis system employing in vitro shuttle transposon mutagenesis has been used to systematically mutagenise the Streptomyces coelicolor genome. To achieve the highest coverage, a new ordered cosmid library was also constructed. Individual cosmids from both the existing and new libraries were disrupted using the Tn5-based mini-transposon Tn5062. A total of 35,358 insertions were sequenced resulting in the disruption of 6,482 genes (83% of the predicted open reading frames). Complete information for both the newly generated cosmids as well as all the insertions has been uploaded onto a central database, StrepDB ( http://strepdb.streptomyces.org.uk/ ). All insertions, new cosmids and a range of transposon exchange cassettes are available for study of individual gene function.
