One-Step Purification and N-Terminal Functionalization of Bioactive Proteins via Atypically Split Inteins.
Article in Bioconjugate chemistry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Site-specific installation of non-natural functionality onto proteins has enabled countless applications in biotechnology, chemical biology, and biomaterials science. Though the N-terminus is an attractive derivatization location, prior methodologies targeting this site have suffered from low selectivity, a limited selection of potential chemical modifications, and/or challenges associated with divergent protein purification/modification steps. In this work, we harness the atypically split VidaL intein to simultaneously N-functionalize and purify homogeneous protein populations in a single step. Our method─referred to as VidaL-tagged expression and protein ligation (VEPL)─enables modular and scalable production of N-terminally modified proteins with native bioactivity. Demonstrating its flexibility and ease of use, we employ VEPL to combinatorially install 4 distinct (multi)functional handles (e.g., biotin, alkyne, fluorophores) to the N-terminus of 4 proteins that span three different classes: fluorescent (Enhanced Green Fluorescent Protein, mCherry), enzymatic (β-lactamase), and growth factor (epidermal growth factor). Moving forward, we anticipate that VEPL's ability to rapidly generate and isolate N-modified proteins will prove useful across the growing fields of applied chemical biology.
