Pyrenoids: CO2-fixing phase separated liquid organelles [PDF]
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2021 Pyrenoids are non-membrane bound organelles found in chloroplasts of algae and hornwort plants that can be seen by light-microscopy. Pyrenoids are formed by liquid-liquid phase separation (LLPS) of Rubisco, the primary CO2 fixing enzyme, with an intrinsically disordered multivalent Rubisco-binding protein.
