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

This statistical study shows that in proteins of gram-negative bacteria exported by the Sec-dependent pathway, the first 14 to 18 residues of the mature sequences have the highest deviation between the observed and expected net charge distributions. Moreover, almost all sequences have either neutral or negative net charge in this region. This rule is restricted to gram-negative bacteria, since neither eukaryotic nor gram-positive bacterial exported proteins have this charge bias. Subsequent experiments performed with a series of Escherichia coli alkaline phosphatase mutants confirmed that this charge bias is associated with protein translocation across the cytoplasmic membrane. Two consecutive basic residues inhibit translocation effectively when placed within the first 14 residues of the mature protein but not when placed in positions 19 and 20. The sensitivity to arginine partially reappeared again 30 residues away from the signal sequence. These data provide new insight into the mechanism of protein export in gram-negative bacteria and lead to practical recommendations for successful secretion of hybrid proteins.
