Project description:Transcriptome analysis based on total RNA-seq was performed on different Haloferax volcanii strains including mutants strains iincluding deletion strains for two small proteins. Differential expression analysis showed that a subset of genes were found to be regulated in the absence of the small proteins.
Project description:Purpose: The Haloferax volcanii ∆tfeB strain provided a unique opportunity to study a putative role of TFEβ in the regulation of gene expression. Results: The deletion of the tfeB gene in H. volcanii results in the aberrant expression of approximately one third of all genes, consistent with its function as a basal transcription initiation factor. Interestingly, tfeB deletion particularly affects foreign genes including a prophage region. Conclusions: Our results confirm the dual function of TFE as basal factor and regulator of transcription
Project description:Identification of global gene expression profiling when Haloferax volcanii H26 strain is grown in minimal medium supplemented with two nitrogen sources, 10 mM L-alanine and 10 mM ammonium chloride.
