Chloroplast-encoded small subunit extensions reshape the Chlamydomonas chlororibosome - Nature Plants
Using in situ cryo-electron tomography, researchers found a unique ‘arm’ domain on the small subunit of Chlamydomonas chlororibosomes. This discovery suggests that chlororibosome structure is more evo...

Florent Waltz@florentwaltz.bsky.social · 6mo agoLong in the making, but happy to present the Chlamydomonas chlororibosome! Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins. bioRxiv 📖: shorturl.at/q44tG This suggests greater chlororibosome diversity than expected! 1/n 🧵
