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

Pasteurella multocida α2-3-sialyltransferase 1 (PmST1) is a multifunctional enzyme which has α2-6-sialyltransferase, α2-3-sialidase, and α2-3-trans-sialidase activities in addition to its major α2-3-sialyltransferase activity. The presence of the α2-3-sialidase activity of PmST1 complicates its application in enzymatic synthesis of α2-3-linked sialosides as the product formed can be hydrolyzed by the enzyme. Herein we show that the α2-3-sialidase activity of PmST1 can be significantly decreased by protein crystal structure-based site-directed mutagenesis. A PmST1 double mutant E271F/R313Y showed a significantly (6333-fold) decreased sialidase activity without affecting its α2-3-sialyltransferase activity. The double mutant E271F/R313Y, therefore, is a superior enzyme for enzymatic synthesis of α2-3-linked sialosides.
