#Carboxysome positioning is not just for #Cyanobacteria!
New preprint from our lab.

The McdAB system positions α-carboxysomes in proteobacteria…

Thread! Carboxysomes are protein-based organelles essential for carbon fixation in cyanobacteria and proteobacteria, and are responsible for almost half of global CO2 fixation. Image

New preprint from the Vecchiarelli lab!

"Cyanobacterial growth and morphology are influenced by carboxysome positioning and temperature"

Work from Rees Rillema @Rees7942 and Joshua MacCready… Like Plants, cyanobacteria use the enzyme RuBisCO to fix CO2 into organic carbon molecules. Unlike plants, cyanobacteria evolved an organelle called the carboxysome - a protein compartment that encapsulates and concentrates RuBisCO along with its CO2 substrate.
