From seawater to pyrenoid: the molecular architecture of the diatom CO2-concentrating mechanism

Abstract. Diatoms are the most successful group of algae and their photosynthesis accounts for up to 20% of annual global CO2 fixation. A key factor to the

Carbonic anhydrase activity under low zinc in Phaeodactylum tricornutum largely depends on metal-free iota-carbonic anhydrase

Abstract. Carbonic anhydrases (CAs) typically possess a Zn2+ cofactor and are involved in a wide range of adaptive metabolisms involving pH and dissolved i

Why do intrinsically disordered proteins behave so weirdly during SDS-PAGE? This is the question we aim to answer in our recent paper: onlinelibrary.wiley.com/doi/10.1002/...

Sequence determinants of the hypomobility of intrinsically disordered proteins in <fc>SDS</fc>‐<fc>PAGE</fc>

Proteins with intrinsically disordered regions (IDRs) migrate at a higher apparent molecular weight in sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis, complicating their analysis and...

Excited to share our latest preprint on #PhycologyFriday. We map out the carbon fixation pathway for the first time in a multicellular alga, the green seaweed Ulva, and reveal a unique Rubisco-Linker interaction in the pyrenoid, a chloroplast condensate. Below I summarize some key points. #seaweeds
