Optimization of the expression of phaC2 encoding poly (3-hydroxyalkanoate) synthase from Pseudomonas aeruginosa PTCC1310 in Fad B deleted Escherichia coli.
Article in Advanced biomedical research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPoly3-hydroxyalkanoates (PHAs) are potential candidates for the industrial production of biodegradable plastics. Therefore, in the present study, expression and activity of one of the enzymes involved in the PHA synthesis, phaC2 (isolated from Pseudomonas aeruginosa PTCC1310), were investigated in Fad B deleted Escherichia coli. MATERIALS AND
methodsThe inserts obtained from recombinant pTZ57R plasmids were ligated into the pGEX-5x-1 expression vector and then transformed into Fad B deleted E. coli cells using the heat shock method. This protein was then expressed using isopropyl beta-d-thiogalactoside (IPTG) as an inducer. By changing expression conditions such as IPTG and glucose concentration, time and temperature of incubation with IPTG, the expression conditions were optimized.
resultsThe optimum condition for the expression of this enzyme was: 1.5 mM IPTG, 1 mM glucose, incubated at 37°C for 2 hours.
conclusionWe obtained functional expression of the phaC2 gene and investigated various conditions that could influence the expression of protein to optimize production of PHA synthase enzymes. This would allow us to study PHA production in large quantities.
