Molecular mechanism of phosphate import by the bacterial PstSCAB transporter.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Inorganic phosphate (Pi) is essential for all living organisms. PstSCAB, a bacterial high-affinity ABC transporter, imports Pi under limiting conditions via five subunits: PstA and PstC forming the transmembrane domain (TMD), periplasmic PstS that switches between free and TMD-docked forms for Pi capture and delivery, and two cytosolic PstB subunits for ATP binding and hydrolysis. Its malfunction affects the virulence of pathogenic bacteria, making it pharmaceutically attractive. However, complete structural pictures of PstSCAB in different states remain lacking. Here, we determine cryo-EM structures of PstSCAB in resting, pretranslocation, and catalytic intermediate states, which reveal that conformational changes in PstS and ATP binding/unbinding in PstB collectively induce rigid-body movements of TMD, generating inward- or outward-facing conformations. In TMD, Pi specificity is determined by positively charged Arg220 (PstA) and Arg237 (PstC). This study advances understanding of bacterial Pi import and supports drug development targeting PstSCAB.
