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

A cDNA expression library of Trichoderma reesei RutC-30 was constructed in the yeast Saccharomyces cerevisiae. Two genes, abf1 and bxl1, were isolated by screening the yeast library for extracellular alpha-L-arabinofuranosidase activity with the substrate p-nitrophenyl-alpha-L-arabinofuranoside. The genes abf1 and bxl1 encode 500 and 758 amino acids, respectively, including the signal sequences. The deduced amino acid sequence of ABFI displays high-level similarity to the alpha-L-arabinofuranosidase B of Aspergillus niger, and the two can form a new family of glycosyl hydrolases. The deduced amino acid sequence of BXLI shows similarities to the beta-glucosidases grouped in family 3. The yeast-produced enzymes were tested for enzymatic activities against different substrates. ABFI released L-arabinose from p-nitrophenyl-alpha-L-arabinofuranoside and arabinoxylans and showed some beta-xylosidase activity toward p-nitrophenyl-beta-D-xylopyranoside. BXLI did not release L-arabinose from arabinoxylan. It showed alpha-L-arabinofuranosidase, alpha-L-arabinopyranosidase, and beta-xylosidase activities against p-nitrophenyl-alpha-L-arabinofuranosidase, p-nitrophenyl-alpha-L-arabinopyranoside, and p-nitrophenyl-beta-D- xylopyranoside, respectively, with the last activity being the highest. It was also able to hydrolyze xylobiose and slowly release xylose from polymeric xylan. ABFI and BXLI correspond to a previously purified alpha-L-arabinofuranosidase and a beta-xylosidase from T. reesei, respectively, as confirmed by partial amino acid sequencing of the Trichoderma-produced enzymes. Both enzymes produced in yeasts displayed hydrolytic properties similar to those of the corresponding enzymes purified from T. reesei.
