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

Uniquely among known ribozymes, the glmS ribozyme-riboswitch requires a small-molecule coenzyme, glucosamine-6-phosphate (GlcN6P). Although consistent with its gene-regulatory function, the use of GlcN6P is unexpected because all of the other characterized self-cleaving ribozymes use RNA functional groups or divalent cations for catalysis. To determine what active site features make this ribozyme reliant on GlcN6P and to evaluate whether it might have evolved from a coenzyme-independent ancestor, we isolated a GlcN6P-independent variant through in vitro selection. Three active site mutations suffice to generate a highly reactive RNA that adopts the wild-type fold but uses divalent cations for catalysis and is insensitive to GlcN6P. Biochemical and crystallographic comparisons of wild-type and mutant ribozymes show that a handful of functional groups fine-tune the RNA to be either coenzyme or cation dependent. These results indicate that a few mutations can confer new biochemical activities on structured RNAs. Thus, families of structurally related ribozymes with divergent function may exist.
