A novel ether core lipid with H-shaped C80-isoprenoid hydrocarbon chain from the hyperthermophilic methanogen Methanothermus fervidus.
A new ether lipid core (designated as FU) was found in Methanothermus fervidus total lipid. Comparison with caldarchaeol showed lower mobility of FU on TLC and smaller molecular weight (m/z 1298) byExpand
Ether polar lipids of methanogenic bacteria: structures, comparative aspects, and biosyntheses.
Complete structures of nearly 40 ether polar lipids from seven species of methanogens have been elucidated during the past 10 years. Three kinds of variations of core lipids, macrocyclic archaeol andExpand
Did Archaeal and Bacterial Cells Arise Independently from Noncellular Precursors? A Hypothesis Stating That the Advent of Membrane Phospholipid with Enantiomeric Glycerophosphate Backbones Caused the
One of the most remarkable biochemical differences between the members of two domains Archaea and Bacteria is the stereochemistry of the glycerophosphate backbone of phospholipids, which areExpand
Extraction and composition of polar lipids from the archaebacterium, Methanobacterium thermoautotrophicum: effective extraction of tetraether lipids by an acidified solvent.
The usual Bligh and Dyer method could extract only a small part of the lipids of Methanobacterium thermoautotrophicum. When the water in the solvent was replaced by 5% trichloroacetic acid, the lipidExpand
Structure determination of a quartet of novel tetraether lipids from Methanobacterium thermoautotrophicum.
The structures of three of the major polar lipids (PNL1a, GL1a, and PNGL1) of Methanobacterium thermoautotrophicum were elucidated. These lipids are derivatives of dibiphytanyl diglycerol tetraetherExpand

Abstract. One of the most remarkable biochemical differences between the members of two domains Archaea and Bacteria is the stereochemistry of the glycerophosphate backbone of phospholipids, whichExpand
sn-glycerol-1-phosphate-forming activities in Archaea: separation of archaeal phospholipid biosynthesis and glycerol catabolism by glycerophosphate enantiomers.
In Methanobacterium thermoautotrophicum, sn-glycerol-1-phosphate (G-1-P) dehydrogenase is responsible for the formation of the Archaea-specific backbone of phospholipids, G-1-P, fromExpand
Lipid molecular species composition of thylakoid membranes.
Lipid molecular species compositions of chloroplast thylakoid membranes of mesophyll cells from Spinacia oleracea, Glycine max, Oryza sativa and Zea mays and of bundle sheath cells from Zea mays haveExpand
Isolation, Characterization and Physiology of a New Formate-assimilable Methanogenic Strain (A2) of Methanobrevibacter arboriphilus
A new methanogenic strain, Methanobrevibacter arboriphilus A2, was isolated from an anaerobic sewage digester in Kitakyushu City, Japan. The isolate was a gram-positive, non-motile short rod, and aExpand
Purification and properties of sn-glycerol-1-phosphate dehydrogenase from Methanobacterium thermoautotrophicum: characterization of the biosynthetic enzyme for the enantiomeric glycerophosphate
The enzyme which seems to be responsible for the formation of the enantiomeric configuration of the glycerophosphate backbone (sn-glycerol-1-phosphate) of archaeal ether lipids was purified from aExpand
