Structural and functional insights into Archaeoglobus fulgidus m2G10 tRNA methyltransferase Trm11 and its Trm112 activator.

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
tRNAs play a central role during the translation process and are heavily post-transcriptionally modified to ensure optimal and faithful mRNA decoding. These epitranscriptomics marks are added by largely conserved proteins and defects in the function of some of these enzymes are responsible for neurodevelopmental disorders and cancers. Here, we focus on the Trm11 enzyme, which forms N2-methylguanosine (m2G) at position 10 of several tRNAs in both archaea and eukaryotes. While eukaryotic Trm11 enzyme is only active as a complex with Trm112, an allosteric activator of methyltransferases modifying factors (RNAs and proteins) involved in mRNA translation, former studies have shown that some archaeal Trm11 proteins are active on their own. As these studies were performed on Trm11 enzymes originating from archaeal organisms lacking TRM112 gene, we have characterized Trm11 (AfTrm11) from the Archaeoglobus fulgidus archaeon, which genome encodes for a Trm112 protein (AfTrm112). We show that AfTrm11 interacts directly with AfTrm112 similarly to eukaryotic enzymes and that although AfTrm11 is active as a single protein, its enzymatic activity is strongly enhanced by AfTrm112. We finally describe the first crystal structures of the AfTrm11-Trm112 complex and of Trm11, alone or bound to the methyltransferase inhibitor sinefungin.
