Expression, purification, and biochemical characterization of micro- and macroalgal kainoid synthases.
Article in Methods in enzymology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Kainoid natural products are a series of potent ionotropic glutamate receptor agonists produced by a variety of divergent marine micro- and macro-algae. The key biosynthetic step in the construction of the pyrrolidine ring pharmacophore involves a unique branch of non-heme iron α-ketoglutarate dependent dioxygenases (Fe/αKGs) termed the kainoid synthases. These Fe/αKG homologs catalyze a stereoselective C-H abstraction followed by a radical carbon-carbon bond reaction to form the bioactive core on N-prenylated L-glutamic acid substrates. In this article, we describe the expression, purification, and biochemical characterization of four divergent kainoid synthases (DabC, RadC1, DsKabC, GfKabC). Furthermore, we compare and contrast their substrate preferences and product distributions, and provide some preliminary insight into how to repurpose these enzymes for whole cell biocatalysis.
