Characterization of a dUTPase from the hyperthermophilic archaeon Thermococcus onnurineus NA1 and its application in polymerase chain reaction amplification.
Article in Marine biotechnology (New York, N.Y.). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Genomic analysis of the hyperthermophilic archaeon Thermococcus onnurineus NA1 (TNA1) revealed the presence of a 471-bp open reading frame with 93% similarity to the dUTPase from Pyrococcus furiosus. The dUTPase-encoding gene was cloned and expressed in Escherichia coli. The purified protein hydrolyzed dUTP at about a 10-fold higher rate than dCTP. The protein behaved as a dimer in gel filtration chromatography, even though it contains five motifs that are conserved in all homotrimeric dUTPases. The dUTPase showed optimum activity at 80 degrees C and pH 8.0, and it was highly thermostable with a half-life (t (1/2)) of 170 min at 95 degrees C. The enzymatic activity of the dUTPase was largely unaffected by variations in MgCl(2), KCl, (NH(4))(2)SO(4), and Triton X-100 concentrations, although it was reduced by bovine serum albumin. Addition of the dUTPase to polymerase chain reactions (PCRs) run with TNA1 DNA polymerase significantly increased product yield, overcoming the inhibitory effect of dUTP. Further, addition of the dUTPase allowed PCR amplification of targets up to 15 kb in length using TNA1 DNA polymerase. This enzyme also improved the PCR efficiency of other archaeal family B type DNA polymerases, including Pfu and KOD.
