    Protein-lipid interaction at low pH induces oligomerization of the MakA cytotoxin from Vibrio cholerae

    Aftab Nadeem, Alexandra Berg ... Sun Nyunt Wai
    MakA, a pore-forming cytotoxin produced by Vibrio cholerae, forms oligomers and remodels membranes into high-curvature tubes, resulting in membrane integrity loss inside acidified organelle lumens or when cultured with cells in an acidic medium.
