Unravelling the secret of antibiotic resistance

Scientists from the University of Leeds have solved a 25-year-old question about how a family of proteins allow bacteria to resist the effects of certain antibiotics. Proteins of the ABC-F protein family are a major source of antibiotic resistance in ‘superbugs’ such as Staphylococcus aureus, a group of bacteria that includes MRSA. The findings provide the first direct evidence of how this family of proteins ‘protect’ the bacterial ribosome, the protein makers in cells, from being blocked by antibiotics.
