Project description:After the prophages of the Vibrio natriegens strain were deleted, RNA-seq experiments were conducted to obtain DGE-profiles in the presence and absence of the two prophages VNP1 and VNP2 in the exponential growth phase.
Project description:After the wild type strain of Vibrio natriegens ATCC 14048 (BioSample Nr. NCBI: SAMN03178087) was cured from prophages (as described in the material and methods section), the genomes of the resulted strains dvnp1, dvnp2 and vnp12 were sequenced. As a control, the genome of the wild type strain was also prepared and used for sequencing. The aim of the sequencing was to verify the deleted regions and to screen the genome for new mutations.
Project description:Regulation of nitrogenase, which converts nitrogen gas (N2) into ammonium (NH4+), typically involves a conserved set of regulatory proteins across diverse N2-fixing (diazotrophic) bacteria. However, the interactions and relative influence of these regulators can vary between species. Thus, one cannot make assumptions about nitrogenase regulation when working with uncharacterized diazotrophs like Vibrio natriegens, a γ-proteobacterium of growing interest for synthetic biology. Here, we characterized the roles of several annotated V. natriegens nitrogenase regulatory proteins in response to NH4+ versus N2. This data set describes the NtrC binding sites in Vibrio natrigens grown with NH4+ versus N2 using chromatin immunopreiciptation combined with combined with massively parallel sequencing (ChIP-seq).
