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

Rieske oxygenase (RO) systems are two- and three-component enzyme systems that catalyze the formation of cis-dihydrodiols from aromatic substrates. Degradation of pollutants in contaminated soil and generation of chiral synthons have been the major foci of RO research. Substrate specificity and product regio- and stereoselectivity have been shown to vary between individual ROs. While directed evolution methods for altering RO function have been successful in the past, rational engineering of these enzymes still poses a challenge due to the lack of structural understanding. Here we examine the structural changes induced by mutation of Phe-352 in naphthalene 1,2-dioxygenase from Pseudomonas sp. strain NCIB 9816-4 (NDO-O(9816-4)). Structures of the Phe-352-Val mutant in native form and in complex with phenanthrene and anthracene, along with those of wild-type NDO-O(9816-4) in complex with phenanthrene, anthracene, and 3-nitrotoluene, are presented. Phenanthrene was shown to bind in a different orientation in the Phe-352-Val mutant active site from that in the wild type, while anthracene was found to bind in similar positions in both enzymes. Two orientations of 3-nitrotoluene were observed, i.e., a productive and a nonproductive orientation. These orientations help explain why NDO-O(9816-4) forms different products from 3-nitrotoluene than those made from nitrobenzene dioxygenase. Comparison of these structures among themselves and with other known ROs bound to substrates reveals that the orientation of substrate binding at the active site is the primary determinant of product regio- and stereoselectivity.
