Project description:We introduce FACIL (http://www.cmbi.ru.nl/FACIL), a fast, reliable tool to evaluate nucleic acid sequences for non-standard codes that detects alternative genetic codes even in species distantly related to known organisms. Results are visualized in a Genetic Code Logo. To illustrate the use of our method, we analysed several contigs derived from the mitochondrial genome of the foraminifer Globobulimina pseudospinescens. These are particularly challenging data, as the genome is highly fragmented and incomplete. Approximately 10,000 single-cell Globobulimina pseudospinescens organisms were isolated by hand from Gullmar Fjord Sweden sediment. After washing, total DNA was extracted and sequenced by Illumina sequencing. The reads were assembled using Edena. To illustrate the use of our method, we analysed several contigs derived from the mitochondrial genome of the foraminifer Globobulimina pseudospinescens, an organism without any sequenced relatives in the databases. These are particularly challenging data, as the genome is highly fragmented and incomplete. DNA isolated from approximately 10,000 single-cell Globobulimina pseudospinescens organisms

Project description:Bacterial transcription factors (TFs) regulate gene expression to adapt to changing environments; when combined, the TF’s regulatory actions comprise transcriptional regulatory networks (TRNs). The chromatin immunoprecipitation (ChIP) assay is the major contemporary method for mapping in vivo protein-DNA interactions in the genome. It enables the genome-wide study of transcription factor binding sites (TFBSs) and gene regulation. Here, we present the genome-wide binding for major TFs in E. coli K-12 MG1655.

The chromatin immunoprecipitation (ChIP) assay is the major contemporary method for mapping in vivo protein-DNA interactions in the genome. It enables the genome-wide study of transcription factor binding sites (TFBSs) and gene regulation. Although rapidly accumulating publicly-available ChIP data are a valuable resource for the study of gene regulation, there are no full datasets of key regulators in Salmonella enterica Typhimurium LT2. Here, we present the genome-wide binding for YdcI in the Salmonella enterica Typhimurium LT2.
