Solution small angle X-ray scattering (SAXS) studies of RecQ from Deinococcus radiodurans and its complexes with junction DNA substrates.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
RecQ helicases, essential enzymes for maintaining genome integrity, possess the capability to participate in a wide variety of DNA metabolisms. They can initiate the homologous recombination repair pathway by unwinding damaged dsDNA and suppress hyper-recombination by promoting Holliday junction (HJ) migration. To learn how DrRecQ participates in the homologous recombination repair pathway, solution structures of Deinococcus radiodurans RecQ (DrRecQ) and its complexes with DNA substrates were investigated by small angle x-ray scattering. We found that the catalytic core and the most N-terminal HRDC (helicase and RNase D C-terminal) domain (HRDC1) undergo a conformational change to a compact state upon binding to a junction DNA. Furthermore, models of DrRecQ in complexes with two kinds of junction DNA (fork junction and HJ) were built based on the small angle x-ray scattering data, and together with the EMSA results, possible binding sites were proposed. It is demonstrated that two DrRecQ molecules bind to the opposite arms of HJ. This architecture is similar to the RuvAB complex and is hypothesized to be highly conserved in the other HJ migration proteins. This work provides us new clues to understand the roles DrRecQ plays in the RecFOR pathway.
