Escherichia coli TatA and TatB Proteins Have N-out, C-in Topology in Intact Cells [PDF]

open access: yes, 2012
The twin arginine protein transport (Tat) system translocates folded proteins across the cytoplasmic membrane of prokaryotes and the thylakoid membrane of chloroplasts.

Selective Synthesis of N,N‐Dimethylformamide From CO2 Hydrogenation Coupled With Dimethylamine Over a ZnZrOx Solid‐Solution Catalyst

open access: yesCarbon and Hydrogen, EarlyView.
N‐formylation of dimethylamine though CO2 hydrogenation takes place at a ZnZrOx solid‐solution catalyst surface toward N,N‐dimethylformamide. By synergistic effect of Zn and Zr sites, the catalyst achieves 99% DMF selectivity at 14% DMA conversion at 280°C with at least 1000 h stability on steam.

Lessons from the operation of the "Penning-Fluorescent" TPC and prospects [PDF]

open access: yes, 2015
We have recently reported the development of a new type of high-pressure Xenon time projection chamber operated with an ultra-low diffusion mixture and that simultaneously displays Penning effect and fluorescence in the near-visible region (300 nm).

Biochemical and structural elucidation of the L-carnitine degradation pathway of the human pathogen Acinetobacter baumannii

open access: yesFrontiers in Microbiology
Acinetobacter baumannii is an opportunistic human pathogen which can use host-derived L-carnitine as sole carbon and energy source. Recently, an L-carnitine transporter (Aci1347) and a specific monooxygense (CntA/CntB) for the intracellular cleavage of L-

Potential TMA-Producing Bacteria Are Ubiquitously Found in Mammalia

open access: yesFrontiers in Microbiology, 2020
Human gut bacteria metabolize dietary components such as choline and carnitine to trimethylamine (TMA) that is subsequently oxidized to trimethylamine-N-oxide (TMAO) by hepatic enzymes.

On the Determination of Trimethylamine and Trimethylamine Oxide

open access: yesNIPPON SUISAN GAKKAISHI, 1957
The extraction of trimethylamine (TMA) with toluene was found to be affected by temperature, sorts of alkali and number of shaking times, as shown in Fig. 1 and Table 1, whereas the color development of TMA with picric acid was not influenced by temperature.

Sequence‐Dependent Heterotypic Assemblies of Intrinsically Disordered Peptides

open access: yesChemistryEurope, EarlyView.
Two oppositely charged intrinsically disordered peptides (IDPs) coassemble into heterotypic nanofibers. Homochiral mixtures (L/L IDPs) form homogeneous, aligned bundles with the more positive IDP. Heterochiral mixtures (L/D IDPs) yield heterogeneous, twisted bundles as positive‐IDP content increases.

Molecular Basis of C–N Bond Cleavage by the Glycyl Radical Enzyme Choline Trimethylamine-Lyase [PDF]

open access: yes, 2018
Deamination of choline catalyzed by the glycyl radical enzyme choline trimethylamine-lyase (CutC) has emerged as an important route for the production of trimethylamine, a microbial metabolite associated with both human disease and biological methane ...

Rescue of morphological defects in Streptomyces venezuelae by the alkaline volatile compound trimethylamine

open access: yesMicrobiology Spectrum
Microorganisms can produce a vast diversity of volatile organic compounds of different chemical classes that are capable of mediating intra- and inter-kingdom interactions. In this study, we showed that the soil-dwelling bacterium Streptomyces venezuelae

From Two‐Electron to Four‐Electron System: Electrolyte Regulation for Advanced Aqueous Zn–I2 Batteries

open access: yesCarbon Energy, EarlyView.
This review systematically summarizes recent progress in electrolyte‐regulated aqueous Zn–I2 batteries (AZIBs). It outlines the fundamentals of AZIBs along with their main challenges, and then analyzes electrolyte‐engineering strategies that improve both two‐ and four‐electron reactions.
