Bacterial ligases reveal fundamental principles of polyubiquitin specificity.
Article in Molecular cell, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Homologous to E6AP C terminus (HECT) E3 ubiquitin (Ub) ligases direct substrates toward distinct cellular fates dictated by the specific form of monomeric or polymeric Ub (polyUb) signal attached. How polyUb specificity is achieved has been a long-standing mystery, despite extensive study in various hosts, ranging from yeast to human. The bacterial pathogens enterohemorrhagic Escherichia coli and Salmonella Typhimurium encode outlying examples of "HECT-like" (bHECT) E3 ligases, but commonalities to eukaryotic HECT (eHECT) mechanism and specificity had not been explored. We expanded the bHECT family with examples in human and plant pathogens. Three bHECT structures in primed, Ub-loaded states resolved key details of the entire Ub ligation process. One structure provided a rare glimpse into the act of ligating polyUb, yielding a means to rewire polyUb specificity of both bHECT and eHECT ligases. Studying this evolutionarily distinct bHECT family has revealed insight into the function of key bacterial virulence factors as well as fundamental principles underlying HECT-type Ub ligation.
