Benzoyl Transfer for Footprinting Alcohol-Containing Residues in Higher Order Structural Applications of Mass-Spectrometry-Based Proteomics.
Article in Analytical chemistry, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Protein footprinting mass spectrometry (MS), an emerging approach to elucidate higher-order structure (HOS) and binding, benefits from the iterative development of reaction strategies to expand the covalent labeling toolbox. Herein, we introduce a footprinting reagent for nucleophiles and demonstrate its efficacy for differential covalent labeling MS analysis. Benzoyl fluoride (BF), although reactive with water, is more practical for modifying nucleophilic functional groups than other acid halides and serves as an acyl-transfer reagent for proteins. BF is 10 times more reactive with phenolic Tyr than the current generation nucleophile footprinter. BF modifies, in addition to Tyr, Lys, His, and the N-terminus, weak nucleophiles Ser and Thr, for which few footprinters exist, imparting broad applicability with a range of nucleophiles. We applied benzoylation to a model Ser- and Thr-rich protein-ligand binding system without perturbing the protein HOS. This efficacious footprinting method expands the toolbox of reagents and provides promise for future reaction strategies including possibly membrane proteins.
