Resolution of Holliday junction recombination intermediates by wild-type and mutant IntDOT proteins.
Article in Journal of bacteriology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
CTnDOT encodes an integrase that is a member of the tyrosine recombinase family. The recombination reaction proceeds by sequential sets of genetic exchanges between the attDOT site in CTnDOT and an attB site in the chromosome. The exchanges are separated by 7 base pairs in each site. Unlike most tyrosine recombinases, IntDOT exchanges sites that contain different DNA sequences between the exchange sites to generate Holliday junctions (HJs) that contain mismatched bases. We demonstrate that IntDOT resolves synthetic HJs in vitro. Holliday junctions that contain identical sequences between the exchange sites are resolved into both substrates and products, while HJs that contain mismatches are resolved only to substrates. This result implies that resolution of HJs to products requires the formation of a higher-order nucleoprotein complex with natural sites containing IntDOT. We also found that proteins with substitutions of residues (V95, K94, and K96) in a putative alpha helix at the junction of the N and CB domains (coupler region) were defective in resolving HJs. Mutational analysis of charged residues in the coupler and the N terminus of the protein did not provide evidence for a charge interaction between the regions of the protein. V95 may participate in a hydrophobic interaction with another region of IntDOT.
