Identification of a protein responsible for the synthesis of archaeal membrane-spanning GDGT lipids

Nature Communications, 2022
The cell membranes of many archaea contain characteristic membrane-spanning lipids known as glycerol dibiphytanyl glycerol tetraethers. Here, Zeng et al.

Planktonic Archaeal Ether Lipid Origins in Surface Waters of the North Pacific Subtropical Gyre

Frontiers in Microbiology, 2021
Thaumarchaeota and Thermoplasmatota are the most abundant planktonic archaea in the sea. Thaumarchaeota contain tetraether lipids as their major membrane lipids, but the lipid composition of uncultured planktonic Thermoplasmatota representatives remains ...

Lipidomic chemotaxonomy aligned with phylogeny of Halobacteria

Frontiers in Microbiology, 2023
Archaea play an important role in global biogeochemical cycles and are considered ancestral to eukaryotes. The unique lipid composition of archaea, characterized by isoprenoid alkyl chains and ether linkage to glycerol-1-phosphate, offers valuable ...

A Novel Approach to Characterize the Lipidome of Marine Archaeon Nitrosopumilus maritimus by Ion Mobility Mass Spectrometry

Frontiers in Microbiology, 2021
Archaea are differentiated from the other two domains of life by their biomolecular characteristics. One such characteristic is the unique structure and composition of their lipids.

Lipidomic diversity and proxy implications of archaea from cold seep sediments of the South China Sea

Frontiers in Microbiology, 2023
Cold seeps on the continental margins are characterized by intense microbial activities that consume a large portion of methane by anaerobic methanotrophic archaea (ANME) through anaerobic oxidation of methane (AOM).

Quantitative Analysis of Core Lipid Production in Methanothermobacter marburgensis at Different Scales

Bioengineering, 2022
Archaeal lipids have a high biotechnological potential, caused by their high resistance to oxidative stress, extreme pH values and temperatures, as well as their ability to withstand phospholipases.

Characterisation of a synthetic Archeal membrane reveals a possible new adaptation route to extreme conditions

Communications Biology, 2021
By studying the properties of a synthetic membrane mimicking an archaeal membrane and containing the apolar polyisoprenoid squalane, Salvador-Castell et al. show that lipid bilayer stability and functionality are shifted to higher temperatures under high

Benthic archaea as potential sources of tetraether membrane lipids in sediments across an oxygen minimum zone [PDF]

Biogeosciences, 2018
Benthic archaea comprise a significant part of the total prokaryotic biomass in marine sediments. Recent genomic surveys suggest they are largely involved in anaerobic processing of organic matter, but the distribution and abundance of these archaeal ...

Bending Elasticity Modulus of Giant Vesicles Composed of Aeropyrum Pernix K1 Archaeal Lipid

Life, 2015
Thermally induced shape fluctuations were used to study elastic properties of giant vesicles composed of archaeal lipids C25,25-archetidyl (glucosyl) inositol and C25,25-archetidylinositol isolated from lyophilised Aeropyrum pernix K1 cells.
