Complexation and evolution of cis-prenyltransferase homologues in Cinnamomum kanehirae deduced from kinetic and functional characterizations.
Article in Protein science : a publication of the Protein Society, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Eukaryotic dehydrodolichyl diphosphate synthases (DHDDSs), cis-prenyltransferases (cis-PTs) synthesizing precursors of dolichols to mediate glycoprotein biosynthesis require partners, for eample Nus1 in yeast and NgBR in animals, which are cis-PTs homologues without activity but to boost the DHDDSs activity. Unlike animals, plants have multiple cis-PT homologues to pair or stand alone to produce various chain-length products with less known physiological roles. We chose Cinnamomum kanehirae, a tree that contains two DHDDS-like and three NgBR-like proteins from genome analysis, and found that one DHDDS-like protein acted as a homodimeric cis-PT to make a medium-chain C55 product, while the other formed heterodimeric complexes with either one of two NgBR homologues to produce longer-chain products. Both complexes were functional to complement the growth defect of the yeast rer2 deficient strain at a higher temperature. From the roles for the polyprenol and dolichol biosynthesis and sequence motifs, their homologues in various species were compared to reveal their possible evolutionary paths.
