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 XYN2 gene encoding the main Trichoderma reesei QM 6a endo-beta-1,4-xylanase was amplified by PCR from first-strand cDNA synthesized on mRNA isolated from the fungus. The nucleotide sequence of the cDNA fragment was verified to contain a 699-bp open reading frame that encodes a 223-amino-acid propeptide. The XYN2 gene, located on URA3-based multicopy shuttle vectors, was successfully expressed in the yeast Saccharomyces cerevisiae under the control of the alcohol dehydrogenase II (ADH2) and phosphoglycerate kinase (PGK1) gene promoters and terminators, respectively. The 33-amino-acid leader peptide of the Xyn2 beta-xylanase was recognized and cleaved at the Kex2-like Lys-Arg residues, enabling the efficient secretion and glycosylation of the heterologous beta-xylanase. The molecular mass of the recombinant beta-xylanase was estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to be 27 kDa. The construction of fur1 ura3 S. cerevisiae strains allowed for the autoselection of the URA3-based XYN2 shuttle vectors in nonselective complex medium. These autoselective S. cerevisiae strains produced 1,200 and 160 nkat of beta-xylanase activity per ml under the control of the ADH2 and PGK1 promoters in rich medium, respectively. The recombinant enzyme showed highest activity at pH 6 and 60 degrees C and retained more than 90% of its activity after 60 min at 50 degrees C.
