Our new preprint is now available! We found a new Group I intron insertion site in tRNA genes of Patescibacteria. These tRNAs were missed by standard tRNA annotation tools. #microbiology #tRNA #Patescibacteria

Phylogenomic analyses indicate the archaeal superphylum DPANN originated from free-living euryarchaeal-like ancestors - Nature Microbiology Phylogenetic reconstructions with conserved protein markers from the 11 known DPANN phyla reveal their monophyletic placement within the Euryarchaeota.

Here, we show that bacterial ribosomes—often viewed as conserved drug targets—actually vary across species due to extensive sequence variation in their drug-binding residues. In some cases, this divergence may lead to intrinsic drug resistance in certain bacterial clades: doi.org/10.1016/j.ce...

Microbe with bizarrely tiny genome may be evolving into a virus With DNA focused almost entirely on replication, newly discovered organism blurs the line between cells and viruses

"With an apparent inability to live outside its host, and with a genome less than half the size of the previously smallest archaeon genome, Sukunaarchaeum is unlike any other archaeon known." ➡️ www.science.org/content/arti... #MicroSky #Archaea

Structurally heterogeneous ribosomes cooperate in protein synthesis in bacterial cells - Nature Communications Cells can simultaneously produce structurally dissimilar ribosomes, suggesting functional specialization of distinct ribosome populations. Here, the authors show that distinct ribosomes cooperate rath...

Here we unexpectedly find that the ribosomal protein S20/L26—identified at the dawn of ribosome research but later deemed a biochemical artifact—is indeed a genuine component of the large ribosomal subunit. More on this ribosome content variation is here: www.nature.com/articles/s41...
