Native MS & Protein Complexes

Oral Presentation

Proteasomes are well-known mediators of intracellular proteostasis, yet their role in the extracellular space remains largely unexplored. Our recent study investigates the molecular architecture and functional specialization of freely circulating 20S proteasomes (c20S) in the bloodstream. Leveraging a CRISPR-engineered transgenic mouse model, we purified c20S complexes and applied a...

16. Flying viruses – mass spectrometry meets X-rays

Native MS & Protein Complexes

Oral Presentation

Viruses affect basically all organisms on earth. Some are detrimental to human development as we experienced during the COVID-19 pandemic, whereas those targeting pathogenic bacteria or crop pathogens can be beneficial for us. An integral part of icosahedral viruses is the capsid protein shell protecting the genome. Many copies of the capsid protein often self-assemble into shells of defined...

7. Filling the Structural Knowledge Gap in Protein Design via Native Mass Spectrometry

Mowei Zhou (Zhejiang University)

Native MS & Protein Complexes

Oral Presentation

Enzymes are powerful molecules for highly efficient and sustainable chemical synthesis. However, natural enzymes often have limitations and require optimization for large-scale industrial applications. Propelled by artificial intelligence, computational advances such as AlphaFold opened new venues for structure-based enzyme design. However, experimental validation still largely relies on high...
