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

Site-specific incorporation of multiple distinct noncanonical amino acids (ncAAs) into a protein is an emerging technology with tremendous potential. It relies on mutually orthogonal engineered aminoacyl-tRNA synthetase/tRNA pairs that suppress different nonsense/frameshift codons. So far, up to two distinct ncAAs have been incorporated into proteins expressed in E. coli, using archaea-derived tyrosyl and pyrrolysyl pairs. Here we report that the E. coli derived tryptophanyl pair can be combined with the archaeal tyrosyl or the pyrrolysyl pair in ATMW1 E. coli to incorporate two different ncAAs into one protein with high fidelity and efficiency. By combining all three orthogonal pairs, we further demonstrate simultaneous site-specific incorporation of three different ncAAs into one protein. To use this technology for chemoselectively labeling proteins with multiple distinct entities at predefined sites, we also sought to identify different bioconjugation handles that can be coincorporated into proteins as ncAA-side chains and subsequently functionalized through mutually compatible labeling chemistries. To this end, we show that the recently developed chemoselective rapid azo-coupling reaction (CRACR) directed to 5-hydroxytryptophan (5HTP) is compatible with strain-promoted azide-alkyne cycloaddition (SPAAC) targeted to p-azidophenylalanine (pAzF) and strain-promoted inverse electron-demand Diels-Alder cycloaddition (SPIEDAC) targeted to cyclopropene-lysine (CpK) for rapid, catalyst-free protein labeling at multiple sites. Combining these mutually orthogonal nonsense suppression systems and the mutually compatible bioconjugation handles they incorporate, we demonstrate site-specific labeling of recombinantly expressed proteins at up to three distinct sites.
