Extending the Peptide/Protein Interaction Paradigm to a Protein/Protein Engagement Model in RiPP Biosynthesis.
Article in ACS chemical biology, 2025. 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
Enzymatic post-translational modification of small precursor peptides generates a wide diversity of bioactive peptidic natural products. The interaction between the precursor peptide and the peptide modifying enzyme relies on recognition of the N-terminal region of the precursor peptide─termed the leader peptide─by the modifying enzyme. In this study, we describe a model for the recognition of atypically long and highly structured nitrile hydratase-like leader peptides (NHLPs) by an azoline forming YcaO cyclodehydratase. Predicated upon the unique structure of NHLPs, the binding model relies on protein/protein interactions between higher-order secondary and tertiary structures of the NHLP and the modifying enzyme. In light of previous findings, we report that different modifying enzymes bind to different molecular surfaces of the NHLPs. These findings illustrate the modularity of different NHLP structural features and how fine-tuning of intermolecular interactions is necessary for efficient catalysis.
