Within the endemic invertebrate faunas of hydrothermal vents, five biogeographic provinces are recognized. Invertebrates at two Indian Ocean vent fields (Kairei and Edmond) belong to a sixth province, despite ecological settings and invertebrate-bacterial symbioses similar to those of both western Pacific and Atlantic vents. Most organisms found at these(More)
Presented here is the complete genome sequence of Thiomicrospira crunogena XCL-2, representative of ubiquitous chemolithoautotrophic sulfur-oxidizing bacteria isolated from deep-sea hydrothermal vents. This gammaproteobacterium has a single chromosome (2,427,734 base pairs), and its genome illustrates many of the adaptations that have enabled it to thrive(More)
We applied two experiments useful in the study of ligand-regulated DNA binding proteins to AraC, the dimeric regulator of the Escherichia coli l-arabinose operon. In the absence of arabinose, AraC prefers to loop DNA by binding to two half-sites that are separated by 210 base pairs, and in the presence of arabinose it prefers to bind to adjacently located(More)

We describe the solution architecture of VisRes-G, a graphical tool for visualising and steering resonance analysis in atomic collision computations. VisRes-G is a comprehensive visual tool that facilitates the graphical display, manipulation and analysis of resonance data computed over the UKL2G. As the user interacts with the graph a collection of(More)
Genes were synthesized to express two DNA binding domains of AraC connected by short linkers. The abilities of the resulting proteins to bind to DNA containing AraC half-sites separated by the usual four bases as well as an additional two or three helical turns of the DNA were measured. The inability of some of the protein constructs to bind to widely(More)
