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

Ubiquitin-like domain 2 (Ubl2) is immediately adjacent to the N-terminus of the papain-like protease (PLpro) domain in coronavirus polyproteins, and it may play a critical role in protease regulation and stability as well as in viral infection. However, our recent cellular studies reveal that removing the Ubl2 domain from MERS PLpro has no effect on its ability to process the viral polyprotein or act as an interferon antagonist, which involves deubiquitinating and deISGylating cellular proteins. Here, we test the hypothesis that the Ubl2 domain is not required for the catalytic function of MERS PLpro in vitro. The X-ray structure of MERS PLpro-∆Ubl2 was determined to 1.9 Å and compared to PLpro containing the N-terminal Ubl2 domain. While the structures were nearly identical, the PLpro-∆Ubl2 enzyme revealed the intact structure of the substrate-binding loop. Moreover, PLpro-∆Ubl2 catalysis against different substrates and a purported inhibitor revealed no differences in catalytic efficiency, substrate specificity, and inhibition. Further, no changes in thermal stability were observed between enzymes. We conclude that the catalytic core of MERS PLpro, i.e. without the Ubl2 domain, is sufficient for catalysis and stability in vitro with utility to evaluate potential inhibitors as a platform for structure-based drug design.
