Substrate-bound structures of yeast ALA synthase reveal protein dynamics initiating heme biosynthesis.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Heme is an essential prosthetic group involved in multiple biological processes in nearly all organisms. Heme biosynthesis is initiated by the pyridoxal 5'-phosphate-dependent enzyme aminolevulinic acid synthase (ALAS). Mutations in ALAS cause multiple hematological diseases. Despite sharing approximately 70% sequence similarity, ALAS homologs exhibit distinct expression and regulatory mechanisms. However, the molecular basis for their functional divergence remains poorly understood. Here, we used x-ray crystallography and molecular dynamics simulations to elucidate the structure and dynamics of
