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 Rieske non-heme iron oxygenases (Rieske oxygenases) comprise a class of metalloenzymes that are involved in the biosynthesis of complex natural products and the biodegradation of aromatic pollutants. Despite this desirable catalytic repertoire, industrial implementation of Rieske oxygenases has been hindered by the multicomponent nature of these enzymes and their requirement for expensive reducing equivalents in the form of a reduced nicotinamide adenine dinucleotide cosubstrate (NAD(P)H). Fortunately, however, some Rieske oxygenases co-occur with accessory proteins, that through a downstream reaction, recycle the needed NAD(P)H for catalysis. As these pathways and accessory proteins are attractive for bioremediation applications and enzyme engineering campaigns, herein, we describe methods for assembling Rieske oxygenase pathways in vitro. Further, using the TsaMBCD pathway as a model system, in this chapter, we provide enzymatic, spectroscopic, and crystallographic methods that can be adapted to explore both Rieske oxygenases and their co-occurring accessory proteins.
