Crystallization and preliminary X-ray crystallographic study of GenX, a lysyl-tRNA synthetase paralogue from Escherichia coli, in complex with translation elongation factor P.
Article in Acta crystallographica. Section F, Structural biology and crystallization communications, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
GenX, a lysyl-tRNA synthetase paralogue from Escherichia coli, was overexpressed in E. coli, purified by three chromatographic steps and cocrystallized with a lysyl adenylate analogue (LysAMS) by the hanging-drop vapour-diffusion method using PEG 4000 as a precipitant. The GenX-LysAMS crystals belonged to the triclinic space group P1, with unit-cell parameters a=54.80, b=69.15, c=94.08 A, alpha=95.47, beta=106.51, gamma=90.46 degrees, and diffracted to 1.9 A resolution. Furthermore, GenX was cocrystallized with translation elongation factor P (EF-P), which is believed to be a putative substrate of GenX, and LysAMS using PEG 4000 and ammonium sulfate as precipitants. The GenX-EF-P-LysAMS crystals belonged to the monoclinic space group P2(1), with unit-cell parameters a=105.93, b=102.96, c=119.94 A, beta=99.4 degrees, and diffracted to 2.5 A resolution. Structure determination of the E. coli GenX-LysAMS and GenX-EF-P-LysAMS complexes by molecular replacement was successful and structure refinements are now in progress.
