Dynamics and Organization of Archaeal Tetraether Lipid Membranes
2017Archaeal bipolar tetraether lipids (BTLs) have distinct structural differences from the lipids isolated from bacteria and eukaryotes. Because of the presence of the unusual structural features, such as macrocyclic structures, cyclopentane rings, isoprenoid units, tetraether linkages, and a variety of polar head groups, archaeal BTL membranes possess ...

Calditol tetraether lipids of the archaebacterium Sulfolobus solfataricus. Biosynthetic studies.
The Biochemical journal, 1990Lipids from the archaebacterium Sulfolobus solfataricus are based on 72-membered macrocyclic tetraethers made up from two C40 diol units differently cyclized and either two glycerol moieties or one glycerol moiety and a unique branched-chain nonitol named calditol (glycerodialkylnonitol tetraethers, GDNTs). To elucidate the biosynthesis of calditol and

The main glycophospholipid from Thermoplasma acidophilum is composed of a diisopranol-2,3-glycerotetraether. The fraction of pentane cyclizations of its hydrocarbon chains increases with the growth temperature of the source organism (39-59 degrees C). Hydrated mixtures of these lipids together with cholesterol have been studied by calorimetry. With the

Structure and permeability properties of biomimetic membranes of bolaform archaeal tetraether lipids
Journal of Membrane Science, 2002This review is a general survey of the properties of membranes formed by tetraether lipids extracted from microorganisms living in extreme conditions, named Archaea. After describing the unusual structure and physico-chemical properties of the membrane-spanning lipids, which allow Archaea to maintain membrane integrity in harsh environments, we ...

An unusual isoprenoid tetraether lipid in marine and lacustrine sediments
Organic Geochemistry, 2008Recent studies have shown that glycerol dialkyl glycerol tetraether (GDGT) lipids, thought be unique for (hyper)thermophilic archaea, are also present in non-thermophilic archaea and environments. In this study, an unusual H-shaped isoprenoid GDGT, in which the two biphytanyl carbon skeletons are covalently bound by a carbon-carbon bond, was ...

Lipids, 2005
AbstractMolecular dynamics simulations of an archaeal membrane made up of bipolar tetraether lipids and a dipalmitoylphosphatidylcholine (DPPC) lipid membrane were performed and compared for the first time. The simulated archaeal membrane consists of a pure monolayer of asymmetrical lipids, analogous to the main polar lipid [MPL; Swain, M., Brisson, J.‐

Fluxes and distribution of tetraether lipids in an equatorial African lake
Geochmica et Cosmochimica Acta, 2009The distribution of isoprenoid and branched glycerol dialkyl glycerol tetraether (GDGT) lipids was studied in material from various sources in and around Lake Challa, a crater lake on the southeastern slope of Mt. Kilimanjaro (Tanzania), to examine the provenance of GDGTs in lake sediments and their potential application as palaeoenvironmental and ...
