The β‐barrel assembly machine (BAM) is essential for folding outer membrane proteins (OMPs) into the outer membrane (OM) of Gram‐negative bacteria. Structures of BAM have been solved using X‐ray crystallography and cryoEM, but the conformation of BAM in the highly crowded native OM remained unsolved. Using EPR spectroscopy of BAM in intact E. coli cells, the structure of BAM in situ has now been revealed...
Poröse aromatische Gerüstmembranen (PAF) mit modifizierbaren Kanälen wurden im Forschungsartikel von Yuyang Tian, Guangshan Zhu et al. synthetisiert (e202113682). Die Porengröße und die Chemie der Membranen konnten durch Ionenaustausch leicht modifiziert werden, was zu geeigneten Membranen für die Trennung verschiedener Gasgemische führte. Mit Br− im Gerüst wies die Membran eine H2/N2‐Selektivität...
