Gene cloning of endoglucanase Cel5A from cellulose-degrading Paenibacillus xylanilyticus KJ-03 and purification and characterization of the recombinant enzyme.
Article in The protein journal, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The bacterial strain Paenibacillus xylanilyticus KJ-03 was isolated from a sample of soil used for cultivating Amorphophallus konjac. The cellulase gene, cel5A was cloned using fosmid library and expressed in Escherichia coli BL21 (trxB). The cel5A gene consists of a 1,743 bp open reading frame and encodes 581 amino acids of a protein. Cel5A contains N-terminal signal peptide, a catalytic domain of glycosyl hydrolase family 5, and DUF291 domain with unknown function. The recombinant cellulase was purified by Ni-affinity chromatography. The cellulase activity of Cel5A was detected in clear band with a molecular weight of 64 kDa by zymogram active staining. The maximum activity of the purified enzyme was displayed at a temperature of 40 °C and pH 6.0 when carboxymethyl cellulose was used as a substrate. It has 44% of its maximum activity at 70 °C and retained 66% of its original activity at 45 °C for 1 h. The purified cellulase hydrolyzed avicel, CMC, filter paper, xylan, and 4-methylumbelliferyl β-D-cellobiose, but no activity was detected against p-nitrophenyl β-D-glucoside. The end products of the hydrolysis of cellotetraose and cellopentaose by Cel5A were detected by thin layer chromatography, while enzyme did not hydrolyze cellobiose and cellotriose.
