A mesophilic, neutrophilic and aerobic, ammonia-oxidizing archaeon, strain EN76T, was
isolated from garden soil in Vienna (Austria). Cells were irregular cocci with a diameter of …

The common idea of typical cell wall architecture in archaea consists of a pseudo-crystalline
proteinaceous surface layer (S-layer), situated upon the cytoplasmic membrane. This is true …

Prokaryotic Argonaute proteins acquire guide strands derived from invading or mobile
genetic elements, via an unknown pathway, to direct guide-dependent cleavage of foreign …

Abstract The Crenarchaeon Ignicoccus hospitalis is an anaerobic, obligate
chemolithoautotrophic hyperthermophile, growing by reduction of elemental sulfur using …

Determining exact viral titers in a given sample is essential for many environmental and
clinical applications, eg, for studying viral ecology or application of bacteriophages for food …

One of the major unanswered questions in evolutionary biology is when and how the
transition between diderm (two membranes) and monoderm (one membrane) cell …

Halophiles are the organisms that thrive in extreme high salt environments. Despite the
extensive studies on their biotechnological potentials, the ability of halophilic prokaryotes for …

Extracellular vesicles (EVs) are endogenous membrane‐derived vesicles that shuttle
bioactive molecules between glia and neurons, thereby promoting neuronal survival and …

Based on serial sectioning, focused ion beam scanning electron microscopy (FIB/SEM), and
electron tomography, we depict in detail the highly unusual anatomy of the marine …

Cytochromes c (Cytc) are widespread electron transfer proteins and important enzymes in
the global nitrogen and sulfur cycles. The distribution of Cytc in more than 300 archaeal …
