Abstract:
Streptomyces are filamentous soil bacteria that produce more
than half of the known microbial antibiotics. We present the
first genome-scale metabolic model of a representative of this
group--Streptomyces coelicolor A3(2). The metabolism
reconstruction was based on annotated genes, physiological and
biochemical information. The stoichiometric model includes 819
biochemical conversions and 152 transport reactions, accounting
for a total of 971 reactions. Of the reactions in the network,
700 are unique, while the rest are iso-reactions. The network
comprises 500 metabolites. A total of 711 open reading frames
(ORFs) were included in the model, which corresponds to 13% of
the ORFs with assigned function in the S. coelicolor A3(2)
genome. In a comparative analysis with the Streptomyces
avermitilis genome, we showed that the metabolic genes are
highly conserved between these species and therefore the model
is suitable for use with other Streptomycetes. Flux balance
analysis was applied for studies of the reconstructed metabolic
network and to assess its metabolic capabilities for growth and
polyketides production. The model predictions of wild-type and
mutants' growth on different carbon and nitrogen sources agreed
with the experimental data in most cases. We estimated the
impact of each reaction knockout on the growth of the in silico
strain on 62 carbon sources and two nitrogen sources, thereby
identifying the "core" of the essential reactions. We also
illustrated how reconstruction of a metabolic network at the
genome level can be used to fill gaps in genome annotation.

Project description:Two component sensor-response regulator systems (TCSs) are very common in the genomes of the Streptomyces species that have been fully sequenced to date. It has been suggested that this large number is an evolutionary response to the variable environment that Streptomyces encounter in soil. Notwithstanding this, TCSs are also more common in the sequenced genomes of other Actinomycetales when these are compared to the genomes of most other eubacteria. In this study, we have used DNA/DNA genome microarray analysis to compare fourteen Streptomyces species and one closely related genus to Streptomyces coelicolor in order to identify a core group of such systems. This core group is compared to the syntenous and non-syntenous TCSs present in the genome sequences of other Actinomycetales in order to separate the systems into those present in Actinomycetales in general, the Streptomyces specific systems and the species specific systems. Horizontal transfer does not seem to play a very important role in the evolution of the TCS complement analyzed in this study. However, cognate pairs do not necessarily seem to evolve at the same pace, which may indicate the evolutionary responses to environmental variation may be reflected differently in sequence changes within the two components of the TCSs. The overall analysis allowed subclassification of the orphan TCSs and the TCS cognate pairs and identification of possible targets for further study using gene knockouts, gene overexpression, reporter genes and yeast two hybrid analysis.

Project description:The whiH gene is required for the differentiation of aerial hyphae into spores in Streptomyces species. It is a predicted member of the GntR family of transcription factors and has been shown to bind specifically to a sequence in its own promoter. This ChIP-Seq experiment was carried out to determine all the binding sites whiH binds to in the genome of Streptomyces venezuelae. A whiH deletion strain was made and a FLAG tagged whiH protein was expressed in it from a genome-integrated plasmid. Then anti-FLAG antibodies were used for chromatin immunoprecipitation followed by high throughput sequencing. The wild type Streptomyces venezuelae strain (ATCC 10712) was used as a negative control. For both the FLAG-WhiH strain and the WT strain, non-immunoprecipitated (total) DNA was also sequenced to arrive at a background enrichment which could be subtracted from the enrichment in the immunoprecipated sample.

Project description:To determine the influence of BldM and WhiI on the binding of each other to their respective binding sites in the genome of Streptomyces venezuelae, ChIP-Seq experiments were carried out using polyclonal antibodies against the wild type proteins as well as anti-FLAG antibodies against FLAG-tagged proteins. Null mutants of Streptomyces venezuelae lacking WhiI or BldM were used as controls. The wild tpe strain was used as control in experiments using the anti-FLAG antibodies.
