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

The Nudix hydrolase superfamily is identified by a conserved cassette of 23 amino acids, and it is characterized by its pyrophosphorylytic activity on a wide variety of nucleoside diphosphate derivatives. Of the 13 members of the family in Escherichia coli, only one, Orf180, has not been identified with a substrate, although a host of nucleoside diphosphate compounds has been tested. Several reports have noted a strong similarity in the three-dimensional structure of the unrelated enzyme, isopentenyl diphosphate isomerase (IDI) to the Nudix structure, and the report that a Nudix enzyme was involved in the synthesis of geraniol, a product of the two substrates of IDI, prompted an investigation of whether the IDI substrates, isopentenyl diphosphate (IPP), and dimethylallyl diphosphate (DAPP) could be substrates of Orf180. This article demonstrates that Orf180 does have a very low activity on IPP, DAPP, and geranyl pyrophosphate (GPP). However, several of the other Nudix enzymes with established nucleoside diphosphate substrates hydrolyze these compounds at substantial rates. In fact, some Nudix hydrolases have higher activities on IPP, DAPP, and GPP than on their signature nucleoside diphosphate derivatives.
