Molecule changes shape to help organisms kick drugs out of cells. Japanese researchers have determined the detailed molecular structure of a protein that rids cells of toxins, but can also reduce the effectiveness of some antibiotics and cancer drugs by kicking them out of the cells they are targeting. The scientists have also identified a molecule that can thwart the activity of the protein, one of a class known as multidrug and toxic compound extrusion transporters (MATEs) that are found in cell membranes. The discovery suggests new approaches to combat antibiotic resistance and boost the power of cancer therapies, the...
