The Escherichia coli DNA binding protein RuvA acts in concert with the helicase RuvB to drive branch migration of Holliday intermediates during recombination and DNA repair. The atomic structure of RuvA was determined at a resolution of 1.9 angstroms. Four monomers of RuvA are related by fourfold symmetry in a manner reminiscent of a four-petaled flower.(More)
Here we present the crystal structure of the Escherichia coli protein RuvA bound to a key DNA intermediate in recombination, the Holliday junction. The structure, solved by isomorphous replacement and density modification at 6 A resolution, reveals the molecular architecture at the heart of the branch migration and resolution reactions required to process(More)
Motion estimation in video is a very important tool for such applications as interpolation, motion compensation, and segmentation. However, in interlaced video, it is often desirable to perform interpolation prior to the motion estimation. In this correspondence, a novel technique is presented that, rather than minimizing the interpolation error in each of(More)
1 This paper describes the development of SDS-FPS, which is a small demand-side model calibrated to match some of the dynamic properties of the Reserve Bank's Forecasting and Policy System (FPS) Core Model. SDS-FPS is capable of matching the dynamic properties of FPS for a wide range of disturbances, despite lacking relative prices, having no explicit(More)
This prospective, randomized trial compares the infection rates of Kirschner wires left percutaneously and those buried deep to the skin in a group of patients with isolated distal radial fractures. Percutaneous wires had a significantly greater infection rate than wires which were buried deep to the skin.
We have determined the structure of Kid toxin protein from E. coli plasmid R1 involved in stable plasmid inheritance by postsegregational killing of plasmid-less daughter cells. Kid forms a two-component system with its antagonist, Kis antitoxin. Our 1.4 A crystal structure of Kid reveals a 2-fold symmetric dimer that closely resembles the DNA(More)
A case is reported of a post-traumatic olecranon bursitis caused by Mycobacterium kansasii following an injury sustained in a public swimming pool. It responded to surgical debridement and combined rifampicin, isoniazid, pyrazinamide and ethambutol antimicrobial therapy. A literature search was performed and a treatment regimen for this uncommon condition(More)
Comparison of the structure of Escherichia coli RuvA with other proteins in the Protein Data Bank gives insights into the probable modes of association of RuvA with the Holliday junction during homologous recombination. All three domains of the RuvA protein possess striking structural similarities to other DNA-binding proteins. Additionally, the second(More)
IL-17A is a pro-inflammatory cytokine produced by the newly identified Th17 subset of T-cells. We have isolated a human monoclonal antibody to IL-17A (CAT-2200) that can potently neutralize the effects of recombinant and native human IL-17A. We determined the crystal structure of IL-17A in complex with the CAT-2200 Fab at 2.6 A resolution in order to(More)
