1 · What the graph read from it

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.

2 · The registry

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

The gene (Bhbgl) encoding a β-glucosidase from the alkalophilic bacterium Bacillus halodurans C-125 was synthesized chemically via the PCR-based two-step DNA synthesis (PTDS) method and expressed in Escherichia coli. Bhbgl contained an open reading frame (ORF) of 1359 bp encoding a 453-amino acid protein belonging to glycoside hydrolase family 1 (GHF1), and the deduced molecular mass of recombinant Bhbgl (52,488 Da) was confirmed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The enzyme exhibited a high specific activity with o-nitrophenyl-β-D-glucopyranoside (oNPGlu) and an apparent K (m) value of 0.32 mM. With oNPGlu as the substrate, Bhbgl displayed pH and temperature optima of ~7.0 and 50°C, respectively. The enzyme was relatively stable under alkaline conditions and >50% activity was retained after incubation at pH 9.5 for 24 h at 4°C. Recombinant Bhbgl activity was inhibited by 5 mM Zn(2+), Fe(3+), or Cd(2+), but was enhanced by 1 mM Mg(2+) and other metal ions. Enzyme activity was also stimulated by at least four sugars (sucrose, D-galactose, xylose, glucose) at concentrations ranging from 50 to 800 mM.
