Molecular cloning, sequencing, and expression of a L -glutamine D-fructose 6-phosphate amidotransferase gene from Volvariella volvacea.
Article in The protein journal, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Using 3'-RACE and 5'-RACE, we have cloned and sequenced the genomic gene and complete cDNA encoding L: -glutamine D: -fructose 6-phosphate amidotransferase (GFAT) from the edible straw mushroom, Volvariella volvacea. Gfat contains five introns, and encodes a predicted protein of 697 amino acids that is homologous to other reported GFAT sequences. Southern hybridization indicated that a single gfat gene locus exists in the V. volvacea genome. Recombinant native V. volvacea GFAT enzyme, over-expressed using Escherichia coli and partially purified, had an estimated molecular mass of 306 kDa and consisted of four equal-sized subunits of 77 kD. Reciprocal plots revealed K (m) values of 0.55 and 0.75 mM for fructose 6-phosphate and L: -glutamine, respectively. V. volvacea GFAT activity was inhibited by the end-product of the hexosamine pathway, UDP-GlcNAc, and by the glutamine analogues N (3)-(4-methoxyfumaroyl)-L: -2,3-diaminopropanoic acid and 2-amino-2-deoxy-D: -glucitol-6-phosphate.
