The Role of Tetraether Lipid Composition in the Adaptation of Thermophilic Archaea to Acidity [PDF]

Frontiers in Microbiology, 2013
Diether and tetraether lipids are fundamental components of the archaeal cell membrane. Archaea adjust the degree of tetraether lipid cyclization in order to maintain functional membranes and cellular homeostasis when confronted with pH and/or thermal ...

Biological Membranes in Extreme Conditions: Simulations of Anionic Archaeal Tetraether Lipid Membranes. [PDF]

PLoS ONE, 2016
In contrast to the majority of organisms that have cells bound by di-ester phospholipids, archaeal membranes consist of di- and tetraether phospholipids.

The influence of near-surface sediment hydrothermalism on the TEX₈₆ tetraether-lipid-based proxy and a new correction for ocean bottom lipid overprinting [PDF]

Biogeosciences, 2022
The diversity and relative abundances of tetraether lipids produced by archaea and bacteria in soils and sediments are increasingly used to assess environmental change.

Engineering archaeal membrane‐spanning lipid GDGT biosynthesis in bacteria: Implications for early life membrane transformations [PDF]

mLife
Eukaryotes are hypothesized to be archaeal–bacterial chimeras. Given the different chemical structures of membrane phospholipids in archaea and bacteria, transformations of membranes during eukaryogenesis that led to the bacterial‐type membranes of ...

Lipid hydrogen isotope compositions primarily reflect growth water in the model archaeon Sulfolobus acidocaldarius [PDF]

Applied and Environmental Microbiology
The stable hydrogen isotope composition (δ2H) of lipid biomarkers can track environmental processes and remain stable over geologically relevant time scales, enabling studies of past climate, hydrology, and ecology.

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 ...

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
