Harnessing synthetic biology to enhance heterologous protein expression.

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 ability to express heterologous proteins in microbial hosts is crucial for many areas of research and technology. In most cases, however, successful expression and purification of the desired protein require fusion to another protein. To date, all fusion partners have been chosen from natural sequences, which evolved for other purposes, and may not be optimal fusion partners. However, the rise of synthetic biology and protein design make it possible to design and optimize fusion proteins using novel sequences that did not arise in nature. Here, we describe a series of De novo Expression Enhancer Proteins (DEEPs) that facilitate high-level expression and facile purification of heterologous proteins and peptides. To test the DEEP system, a de novo protein was fused to several target proteins covering a range of sizes and solubilities. In all cases, fusions to DEEP outperformed fusions to SUMO, a commonly used natural fusion partner. The availability of novel proteins that can be engineered for specific fusion applications could be beneficial to enhance the expression of a wide range of heterologous proteins.
