Woese and Fox's 1977 paper on the discovery of the Archaea triggered a revolution in the
field of evolutionary biology by showing that life was divided into not only prokaryotes and …

Phospholipids are essential components of biological membranes and are involved in cell
signalization, in several enzymatic reactions, and in energy metabolism. In addition …

The principles for the selection of the stereochemistry of phospholipids of biological
membranes remain unclear and continue to be debated. Therefore, any new experiments on …

Asgard is an archaeal superphylum that might hold the key to understand the origin of
eukaryotes, but its diversity and ecological roles remain poorly understood. Here, we …

Nucleotides, amino acids, sugars, and lipids are almost ubiquitously homochiral within
individual cells on Earth. While oligonucleotides and proteins exist as one natural chirality …

Membrane lipid chemistry is remarkably different in archaea compared with bacteria and
eukaryotes. In the evolutionary context, this is also termed the lipid divide and is reflected by …

Abstract Phosphatidylglycerol (1, 2-diacyl-sn-glycero-3-phospho-glycerol)(PG) is one of the
most abundant lipids in bacteria. However, the chirality of the carbon atom on glycerol …

One of the key differences between Bacteria and Archaea is their canonical membrane
phospholipids, which are synthesized by distinct biosynthetic pathways with …

The major archaeal membrane glycerolipids are distinguished from those of bacteria and
eukaryotes by the contrasting stereochemistry of their glycerol backbones, and by the use of …

The existence of LUCA in the distant past is the logical consequence of the binary
mechanism of cell division. The biosphere in which LUCA and contemporaries were living …
