NUTRITIONAL MUTATIONS AND TRANSDUCTION BY ULTRAVIOLET-INACTIVATED PHAGE IN STAPHYLOCOCCUS AUREUS.

abstract：:Vibrio cholerae hemolysin (HlyA) is a 65-kDa water-soluble pore-forming toxin that causes lysis of eukaryotic cells by destroying selective permeability of the plasma membrane bilayer. The HlyA monomer self-assembles on the target cell surface to the more stable beta-barrel amphipathic heptamer, which inserts into the...
