Regulation of blood–brain barrier integrity by microbiome-associated methylamines and cognition by trimethylamine N-oxide [PDF]

Microbiome, 2021
Background Communication between the gut microbiota and the brain is primarily mediated via soluble microbe-derived metabolites, but the details of this pathway remain poorly defined. Methylamines produced by microbial metabolism of dietary choline and l-

Widespread atypical response regulator SecR governs bacterial growth on methylamines through the serine cycle [PDF]

Communications Biology
Microbial utilization of methylamines (MAs) exerts profound effects on biogeochemical carbon cycles, yet the regulatory mechanisms enabling bacterial adaptation to fluctuating MAs availability remain elusive.

Metagenomic evidence of suppressed methanogenic pathways along soil profile after wetland conversion to cropland

Frontiers in Microbiology, 2022
Wetland conversion to cropland substantially suppresses methane (CH4) emissions due to the strong suppression of methanogenesis, which consists of various pathways.

Mineralogical control on methylotrophic methanogenesis and implications for cryptic methane cycling in marine surface sediment

Nature Communications, 2022
Adsorption of methylamines onto clay minerals provides a hitherto unrecognised control on methane production in marine surface sediment.

Evidence of Interdomain Ammonium Cross-Feeding From Methylamine- and Glycine Betaine-Degrading Rhodobacteraceae to Diatoms as a Widespread Interaction in the Marine Phycosphere

Frontiers in Microbiology, 2020
Dissolved organic nitrogen (DON) compounds such as methylamines (MAs) and glycine betaine (GBT) occur at detectable concentrations in marine habitats and are also produced and released by microalgae.

Salt potentiates methylamine counteraction system to offset the deleterious effects of urea on protein stability and function. [PDF]

PLoS ONE, 2015
Cellular methylamines are osmolytes (low molecular weight organic compounds) believed to offset the urea's harmful effects on the stability and function of proteins in mammalian kidney and marine invertebrates. Although urea and methylamines are found at

Cryoprotective Metabolites Are Sourced from Both External Diet and Internal Macromolecular Reserves during Metabolic Reprogramming for Freeze Tolerance in Drosophilid Fly, Chymomyza costata

Metabolites, 2022
Many cold-acclimated insects accumulate high concentrations of low molecular weight cryoprotectants (CPs) in order to tolerate low subzero temperatures or internal freezing.

The influence of chemical chaperones on enzymatic activity under thermal and chemical stresses: common features and variation among diverse chemical families. [PDF]

PLoS ONE, 2014
Molecular and chemical chaperones are key components of the two main mechanisms that ensure structural stability and activity under environmental stresses.
