Congrats to the authors on a beautiful study! 🥳 Very elegant dissection of #LLPS by Rubisco inside the pyrenoid. Our Ape1’s linker is N-terminal, here it’s a separate protein—yet the physics feels strikingly similar. Cryo-ET of disordered networks is tough, but that’s why this work is so impressive.
Excited to share this detailed biophysical study of #PhaseSeparation in the Pyrenoid, an algal microcompartment that fixes a third of the Earth's #CO2 🌏. We combine methods across scales, in vitro 🧪 and in vivo 🦠
Thanks for the very fun collaboration! 🤗

How does molecular valency shape condensate assembly and function? We used the CO2-fixing organelle in algae—the pyrenoid—to find out… 🧵

We are very excited to see this work out in its final form at Ultramicroscopy! Knife edge measurements of beam shapes and improved scanned versus shaped beam material removal comparisons. Find the OA article here: doi.org/10.1016/j.ul...
