Figure - on the left: the atomic structure of the protein segment that forms the biofilm fibers in E. coli and Salmonella. This structure is very similar to the structures of amyloid fibers associated with Alzheimer's disease, and this structural similarity led to the idea of ​​damaging the bacterial biofilm fibers using the substances developed against Alzheimer's fibers. Above (in black and white): images taken with an electron microscope. On the left are visible fibers that are formed by the bacterial protein and are used to build the biofilm; On the right is shown the damage to fiber formation as a result of the addition of the substance that opens Alzheimer's fibers (ANK6) Below (in black-red): 6D images taken with a confocal microscope after red fluorescent staining of the bacterial biofilm. Left: high density of biofilm; Right: a significant decrease in the amount of biofilm following the addition of the substance ANKXNUMX.

Although their name was given to them due to their function on the tongue, the bitter and sweet taste receptors were recently discovered in various tissues and organs that do not come into contact with food. In at least some of these areas of the body, especially the respiratory tract, these taste receptors play an important role in the immune response. Illustration: pixabay.

Cross section of the large subunit of the bacterial ribosome. In yellow - the exit tunnel of the proteins from the ribosome. In red - the binding pocket of erythromycin at the entrance to the tunnel. Bottom right (marked in light blue) – the ribosomal protein L22. In structural and chemical terms, the protein is distant from the binding pocket of the antibiotic.
