Probing the Interaction between HIV-1 Protease and the Homodimeric p66/p66' Reverse Transcriptase Precursor by Double Electron-Electron Resonance EPR Spectroscopy.
Article in Chembiochem : a European journal of chemical biology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Following excision from the Gag-Pol polyprotein, HIV-1 reverse transcriptase is released as an asymmetric homodimer comprising two p66 subunits that are structurally dissimilar but identical in amino acid sequence. Subsequent cleavage of the RNase H domain from only one of the subunits, denoted p66', results in the formation of the mature p66/p51 enzyme in which catalytic activity resides in the p66 subunit, and the p51 subunit (derived from p66') provides a supporting structural scaffold. Here, we probe the interaction of the p66/p66' asymmetric reverse transcriptase precursor with HIV-1 protease by pulsed Q-band double electron-electron resonance EPR spectroscopy to measure distances between nitroxide labels introduced at surface-engineered cysteine residues. The data suggest that the flexible, exposed linker between the RNaseH and connection domains in the open state of the p66' subunit binds to the active site of protease in a configuration that is similar to that of extended peptide substrates.
