Functionalized Membrane Domains: An Ancestral Feature of Archaea?

Frontiers in Microbiology, 2020
Bacteria and Eukarya organize their plasma membrane spatially into domains of distinct functions. Due to the uniqueness of their lipids, membrane functionalization in Archaea remains a debated area. A novel membrane ultrastructure predicts that monolayer

Biocatalytic Ether Lipid Synthesis by an Archaeal Glycerolprenylase

Angewandte Chemie International Edition
Although ethers are common in secondary natural products, they are an underrepresented functional group in primary metabolism. As such, there are comparably few enzymes capable of constructing ether bonds in a general fashion. However, such enzymes are highly sought after for synthetic applications as they typically operate with higher regioselectivity

The essence of being extremophilic: the role of the unique archaeal membrane lipids:the role of the unique archaeal membrane lipids

, 1998
In extreme environments, mainly Archaea are encountered. The archaeal cytoplasmic membrane contains unique ether lipids that cannot easily be degraded, are temperature- and mechanically resistant, and highly salt tolerant.

A laboratory experiment of intact polar lipid degradation in sandy sediments [PDF]

Biogeosciences, 2011
Intact polar lipids (IPLs) are considered biomarkers for living biomass. Their degradation in marine sediments, however, is poorly understood and complicates interpretation of their occurrence in geological samples. To investigate the turnover of IPLs, a

Tree species identity is associated with rhizosphere microbiome assembly via root metabolite‐mediated feedbacks in subtropical forests

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rhizosphere microbiome is critical for forest ecological functions, yet the mechanisms through which tree species identity and neighbour tree interactions are associated with its assembly remain poorly understood.

Seasonal Dynamics of Community and Function of Gut Microbiome in Taihangshan Macaque (Macaca mulatta tcheliensis): Inferred From Metagenomic Data

Integrative Zoology, EarlyView.
A total of 435 non‐redundant metagenome‐assembled genomes (MAGs) were obtained from fecal samples of Taihangshan macaque across all four seasons. The alpha diversity of the gut microbiome in spring and winter was significantly higher than in summer and autumn. Furthermore, marked differences were detected in functional pathways and carbohydrate enzymes

Archaeal phospholipids:Structural properties and biosynthesis [PDF]

, 2017
Phospholipids are major components of the cellular membranes present in all living organisms. They typically form a lipid bilayer that embroiders the cell or cellular organelles, constitute a barrier for ions and small solutes and form a matrix that ...

Lipid-protein stoichiometries in a crystalline biological membrane: NMR quantitative analysis of the lipid extract of the purple membrane

Journal of Lipid Research, 2002
The lipid/protein stoichiometries of a naturally crystalline biological membrane, the purple membrane (PM) of Halobacterium salinarum, have been obtained by a combination of 31P- and 1H-NMR analyses of the lipid extract.

Seasonal Difference of Gut Microbiota at a Stopover Site in Five Passerines of Different Migratory Behavior

Integrative Zoology, EarlyView.
Seasonal variation significantly reshaped gut microbiota composition in migratory passerine species, whereas the resident species Suthora webbiana showed no clear seasonal shift. Species with similar migratory behaviors exhibited consistent seasonal patterns in their core gut microbiota.

Folate PEGylated archaeal lipids: cell targeting and drug delivery.

, 2010
International audienceArchaeosomes are of interest for potential biotechnological applications such as biomaterial delivery. Indeed, the archaeal lipid analogues improve the stability of delivery systems, including oral administration [1,2]. We developed
