A novel class of conserved sucrose-phosphate phosphatases highlights the diversity of cyanobacterial sucrose metabolism
Sucrose metabolism is an important feature of the physiology of the green lineage of photosynthetic organisms and has therefore been the subject of considerable research on plants, algae, and cyanobac...

I am so thrilled to share our new publication. We found that carboxysome losses integrity in response to ROS and PQ pool overreduction. RpaA seems to have an important role in controlling the organization of carboxysomes. For more details, here is the link: onlinelibrary.wiley.com/doi/10.1111/...

Plastoquinone redox status influences carboxysome integrity via a RpaA‐ and reactive oxygen species‐dependent regulatory network
We identified a dramatic remodeling of carboxysomes under conditions that lead to overreduction of the plastoquinone pool of the photosynthetic electron transport chain. This overreduction was accomp...
