MatE transporter affects methane metabolism in Methermicoccus shengliensis and is modulated by methoxylated aromatic compounds.

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
Methoxylated aromatic compounds, are abundant in subsurface ecosystems. Recently, it was discovered that Methermicoccus shengliensis can convert methoxylated aromatics to methane. Specifically, the MATE family transporters (MatE) and transduction-like protein (Tlp) were hypothesized to play a crucial role in substrate transport. However, their biological function and the transporting model remained unclear. To address this knowledge gap, we employed bacterial two-hybrid and structural model assays to investigate the interaction between Tlp and MatE. Our results revealed that Tlp senses 2-methoxybenzoate and interacts with MatE to facilitate substrate transport. Furthermore, we observed that the matE knock-out mutant significantly impaired the growth and methane production of M. shengliensis when using 2-methoxybenzoate as a substrate, highlighting the essential role of MatE in methoxydotrophic methanogenesis. Overall, our findings suggest that the MatE-Tlp system regulates substrate uptake and methane metabolism in M. shengliensis, providing new avenues for reducing global methane emissions caused by methanogens.
