Structural biologist using #cryoEM ❄️🔬 I feel more at home on the Fediverse at fediscience.org/@Guillawme

"Is X-ray crystallography dead?" some asked when cryoEM got momentum. Depends on what you work on. For nucleosomes it certainly looks like it is dead: all structures with nucleosomes released in 2023 were cryoEM structures! @nucleosomepolice.bsky.social guillawme.github.io/insights-fro...

Bar graph showing the number of PDB entries containing a nucleosome released every year since 1997 (one structure). Crystal structures are red bars, cryoEM structures are green bars. In 2023, all PDB entries with a nucleosome were cryoEM structures.

(The big slow-down caused by the quarantines during the COVID-19 pandemic is also very apparent when comparing the bars for 2019 and 2020...)
