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

Myriad new applications of proteases would be enabled by an ability to fine-tune substrate specificity and activity. Herein we present a general strategy for engineering protease selectivity and activity by capitalizing on sequestration of the protease to be engineered within the yeast endoplasmic reticulum (ER). A substrate fusion protein composed of yeast adhesion receptor subunit Aga2, selection and counterselection substrate sequences, multiple intervening epitope tag sequences, and a C-terminal ER retention sequence is coexpressed with a protease library. Cleavage of the substrate fusion protein by the protease eliminates the ER retention sequence, facilitating transport to the yeast surface. Yeast cells that display Aga2 fusions in which only the selection substrate is cleaved are isolated by multicolor FACS with fluorescently labeled antiepitope tag antibodies. Using this system, the Tobacco Etch Virus protease (TEV-P), which strongly prefers Gln at P1 of its canonical ENLYFQ↓S substrate, was engineered to recognize selectively Glu or His at P1. Kinetic analysis indicated an overall 5,000-fold and 1,100-fold change in selectivity, respectively, for the Glu- and His-specific TEV variants, both of which retained high catalytic turnover. Human granzyme K and the hepatitis C virus protease were also shown to be amenable to this unique approach. Further, by adjusting the signaling strategy to identify phosphorylated as opposed to cleaved sequences, this unique system was shown to be compatible with the human Abelson tyrosine kinase.
