1 · What the graph read from it

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.

2 · The registry

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

Knowledge on domain swapping in vitro is increasing, but domain swapping may not occur regularly in vivo, and its information in cells is limited. Herein, we show that domain-swapped oligomers of a thermostable c-type cytochrome, Hydrogenobacter thermophilus cyt c552, are formed in E. coli which expresses cyt c552. The region containing the N-terminal α-helix and heme was domain-swapped between protomers in the dimer formed in E. coli. The amount of cyt c552 oligomers increased in E. coli as the cyt c552 concentration was increased, whereas that of high-order oligomers decreased in the order of decrease in protein stability, indicating that domain swapping decreases in cells when the protein stability decreases. Apo cyt c552 was detected in the cyt c552 oligomer formed in E. coli, but not in that of the A5F/M11V/Y32F/Y41E/I76V mutant. The cyt c552 oligomer containing its apo protein may form at the periplasm, since the apo protein detected by mass measurements did not contain the signal peptide. These results show that domain-swapped cyt c552 oligomers were formed in E. coli, owing to the stability of the transient oligomer containing the apo protein before heme attachment. This is an indication that exceedingly stable proteins may have disadvantages forming domain-swapped oligomers in cells.
