1 · What the graph read from it

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.

2 · The registry

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

In Yersinia enterocolitica biovar 1B, a genome encoded TTSS designated as Ysa-Ysp system is used for virulence. SycB is an annotated chaperone to this system. SycB is soluble in presence of translocator YspC. SycB and its truncated form (∆SycB((1-114))) exist as dimers. YspC forms a 1:1 complex with SycB. Homology model of SycB shows a flexible N-terminal may be required for solubility and dimerization; and concave core formed by antiparallel helices of TPRs. Far UV CD spectra confirm that SycB is predominantly alpha helical. Near UV CD spectra show that SycB has tertiary structure at pH 7.2 (native folded protein), which disappears at pH 5 (molten globule) and SycB releases YspC at pH 5. SycB has a cooperative melting behavior. At pH 7.2, SycB shows solvent accessible hydrophobic patches. Concave core in the model exhibits ANS binding within FRET distance of tyrosines in the TPR, allowing a range of interaction of SycB with its ligand.
