Structural characterization and heterologous expression of a new cyt gene cloned from Bacillus thuringiensis.
Article in Journal of molecular modeling, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Bacillus thuringiensis (Bt) strains produce Cry (crystal) and Cyt (cytolytic) proteins belonging to the group of bacterial toxins known as pore-forming toxins (PFTs), which interact with midgut cells of target insects to create pores, disruption of ion homeostasis and eventual death. PFTs have synergistic insecticidal activities and have been used as biopesticides against agriculturally important insects. Identification of new Cyt proteins is important because of their specific toxicity towards hemipteran pests, against which the Cry proteins are not effective. We have structurally characterized a cyt (cyt1007) gene from an Indian Bt isolate SK-1007. The presence of a "Bacillus thuringiensis toxin" domain and maximum identity of 36% with Cyt2Ca in the deduced amino acid sequence indicated Cyt1007 protein to be a new member of Cyt family. Three dimensional (3D) modeling (PMDB ID: PM0081490) revealed that it adopts a typical ferredoxin-like fold, and is composed of a single domain of α/β architecture, in which a single β sheet is surrounded by two α helical layers. The putative lipid binding site and probable mode of action of Cyt1007 protein were predicted through comparative analysis with other Cyt toxins and their distant homologs Evf (Erwinia virulence factor) and VVA2 (Volvatoxin A2). Heterologous expression of cyt1007 gene as a 25 kDa protein in Escherichia coli was achieved at high levels in both soluble and insoluble fractions. Affinity chromatography-based purification yielded 83.6% purified Cyt1007 protein, which can be used for downstream applications for the investigation of its toxicity. Graphical abstract Steps in the structural characterization and heterologous expression of a new cyt gene cloned from Bacillus thuringiensis.
