Origin of product selectivity in a prenyl transfer reaction from the same intermediate: exploration of multiple FtmPT1-catalyzed prenyl transfer pathways.

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
FtmPT1 is a fungal indole prenyltransferase that catalyzes the reaction of tryptophan derivatives with dimethylallyl pyrophosphate to form various biologically active compounds. Herein, we describe detailed studies of FtmPT1 catalysis involving dimethylallyl pyrophosphate and Brevianamide F following the native pathway (yielding Tryprostatin B) and an alternate pathway observed in the Gly115Thr mutant of FtmPT1 yielding a novel cyclized product. Importantly, these two products arise from the same intermediate state, meaning that a step other than the cleavage of the dimethylallyl pyrophosphate (DMAPP; C-O) bond is differentiating between the two product reaction channels. From detailed potential of mean force (PMF) and two-dimensional PMF analyses, we conclude that the rate-limiting step is the cleavage of the C-O bond in DMAPP, while the deprotonation/cyclization step determines the final product distribution. Hence, in the case of FtmPT1, the optimization of the necessary catalytic machinery guides the generation of the final product after formation of the intermediate carbocation.
