Molecular dynamics study of hell's gate globin I (HGbI) from a methanotrophic extremophile: oxygen migration through a large cavity.

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
Hell's gate globin I (HGbI), a heme-containing protein from the extremophile Methylacidiphilum infernorum, has fast oxygen-binding/slow release characteristics due to its distal residues Gln and Tyr. The combination of Gln/Tyr distal iron coordination, adaptation to extreme environmental conditions, and lack of a D helix suggests that ligand migration in HGbI differs from other previously studied globins. Locally enhanced molecular dynamics trajectories of oxygen migration indicate a large internal cavity. This may increase the tendency of oxygen to exit from portals other than the most direct exit from the space near the heme. Oxygen may reside transiently in shallow surface depressions around the exits. Such surface trapping may enhance both oxygen uptake by increasing contact time between molecules, and decrease release by increasing the probability of oxygen reentry from the vicinity of the portal.
