#archea — Public Fediverse posts

Humanity should not expect to be able to communicate with extraterrestrial life, considering that there are hardly any life forms on Earth that we are able to fully communicate with. How many species of plants, bacteria, archea, or protists can humans fully communicate with?

Gaze over this beautiful detail of the archeal ribosome, with the archea-only proteins in red. (The very core of the ribosome is thought to almost never change across all life)

Then have a look at the amazing H-bonding network of the catalytic peptide transfer ribosomal-RNA site (Fig. 2). The tRNA entry point gets blocked by a unique protein "dual ribosomal subunit inhibitor (Dri)" under stress conditions and locks everything into place (Fig. 4).

"Ribosomes translate mRNA into protein. Despite divergence in ribosome structure over the course of evolution, the catalytic site, known as the peptidyl transferase centre (PTC) is thought to be nearly universally conserved. Here we identify clades of archaea that have highly divergent ribosomal RNA sequences in the PTC."

Some plants are able to control soil nitrification by interfering with the activity of nitrifying bacteria and archea. Ardichvili et al. explore the consequences of control and plant preference for ammonium vs. nitrate on ecosystem productivity and more.
