BRIDGE : a bioinformatics software platform for the integration of heterogeneous data from genomic explorations
… from the increasing number of publicly available prokaryote genomes has led to new demands for bioinformatics software. With the growing amount of information resulting from high-throughput experiments new questions arise that often focus on the comparison of genes, genomes and their expression …

Geobiology of marine magnetotactic bacteria
… the greigite-producing many-celled magnetotactic prokaryote (MMP), and a greigite-producing rod. The barbells were identified as [delta]-Proteobacteria while the rod was identified as the first MTB in the [gamma]-Proteobacteria.

Partial structural characterization of the cytoplasmic hemoglobin of Nostoc commune UTEX 584 expressed in Escherichia coli
… is the first monomeric hemoglobin detected in a prokaryote, raising questions concerning a possible role of cyanoglobin in early globin gene evolution.

Geochemical investigation of the co-evolution of life and environment in the Neoproterozoic Era
… on an important juncture—the transition from prokaryote to eukaryote dominance in marine ecosystems during the Tonian Period (1000 Ma to 720 Ma). To assess whether the availability of nitrate, an important macro-nutrient, played a critical role in this evolutionary event, nitrogen isotope …

A regulatory role for repeated decoy transcription factor binding sites in target gene expression
Repetitive DNA sequences are prevalent in both prokaryote and eukaryote genomes and the majority of repeats are concentrated in intergenic regions. These tandem repeats (TRs) are highly variable as the number of repeated units changes frequently due to recombination events and/or polymerase …

Novel Cell Surface Anchoring Mechanism Of Prokaryotic Secreted Protein
… lipid-anchoring mechanism described for any prokaryote. Furthermore, I have shown that this process is also ArtA-dependent and that the substrate conserved PGF motif is critical for processing and lipid anchoring. This novel anchoring mechanism is not limited to SLG, as I have demonstrated …

Eukaryotic Microbes in the Deep Sea: Abundance, Diversity, and the Effect of Pressure
… abundances decrease much more sharply than prokaryote abundances with depth, though most of this decrease occurs in the upper 1000 m, below which eukaryote abundance is relatively constant. In water masses below 1000 m, 50-70% of total eukaryotes detected by CARD-FISH can be attributed to …

Geobiology of marine magnetotactic bacteria
… the greigite-producing many-celled magnetotactic prokaryote (MMP), and a greigite-producing rod. The barbells were identified as δ-Proteobacteria while the rod was identified as the first MTB in the γ-Proteobacteria. The MMP, previously thought to be a single species, consists of at least five …

Bacterioplankton community composition and activity in the Atlantic Ocean
… abundance and integrated biomass<br/>of three prokaryote groups (Prochlorococcus spp., Synechococcus spp. and heterotrophic<br/>bacteria) were used to detect standing stock changes and characterise community<br/>structure in the Northern and Southern oligotrophic gyres and in the equatorial …

Aspects of the biology of Mya arenaria and Ensis spp. (Mollusca; Bivalvia) in the Irish Sea and adjacent areas
… conditions were observed in M. arenaria while Prokaryote inclusions, trematode parasites, Nematopsis spp. and inflammatory pathologies were observed at low incidences in razor clams from Ireland but not from Wales; the first time these conditions have been reported in Ensis spp. in northern …

Gene Expression Control for Synthetic Patterning of Bacterial Populations and Plants
… polymerase-driven synthetic patterning from the prokaryote E. coli to the eukaryote M. polymorpha, I developed a toolbox of genetic elements for spatial gene expression control in the liverwort: I analyzed codon usage across the transcriptome of M. polymorpha, and used insights gained to design …

Ancestral Genome Reconstruction in Bacteria
… Furthermore, we build our in-house Prokaryote Genome Evolution simulator (PEGsim) for evaluation purposes. The homologous gene family prediction refinement module can refine homologous gene family predictions generated by third party de novo prediction programs by combining phylogeny …

Protein O-Kinases in the Archaeon Sulfolobus solfataricus
For many years, it has been understood that protein phosphorylation-dephosphorylation constitutes one of the most ubiquitous mechanisms for controlling the functional properties of proteins. Although originally believed to be a eukaryotic phenomenon, protein phosphorylation is now known to occur in …

Rarely Acquired Type II-A CRISPR-Cas Spacers Mediate Anti-Viral Immunity Through the Targeting of a Non-Canonical PAM Sequence
<p>Viruses that infect prokaryotes, called bacteriophages or phages, are thought to outnumber bacteria by a ratio of 10:1 and provide a constant threat to their hosts. In response, bacteria have evolved numerous defense mechanisms, attacking all major steps of the phage infection and replication …

Electrogenetic pathways in cyanobacteria
… *nox* genes and a possible eukaryote-to-prokaryote horizontal gene transfer event. These results provide valuable information for the identification of electrogenetic components in cyanobacteria and lay the groundwork for the experimental investigations presented in the following …
