Phosphate backbone epitranscriptomics: Discovery of natural RNA phosphorothioates and their writer machinery.

Over 150 modifications expand the RNA alphabet, yet all known natural modifications occur on nucleobases or ribose sugars, with none identified on the phosphate backbone. In contrast, phosphorothioates (PSs), in which a non-bridging phosphate oxygen is replaced with sulfur, are central to RNA therapeutics but have neve...

A methanogen hydrolase reveals the structure of archaeal peptidoglycan.

Structural basis of nucleosome remodeling by archaeal RNA polymerase during transcription elongation

Transcription occurs in the context of histone-based chromatin in eukaryotes and most archaea. The archaeal RNA polymerase and histones are ancestral to their eukaryotic counterparts, yet how RNA polymerase traverses histone-bound DNA in archaea remains poorly understood. Here, we reconstitute a nucleosome-associated t...
