Protein study gives fresh impetus in fight against superbugs

Scientists have shed new light on the way superbugs such as MRSA are able to become resistant to treatment with antibiotics.

Researchers have mapped the complex molecular structure of an enzyme found in many bacteria. These molecules – known as restriction enzymes – control the speed at which bacteria can acquire resistance to drugs and eventually become superbugs.

The study, carried out by an international team including scientists from the University of Edinburgh, focused on E. coli, but the results would apply to many other infectious bacteria.
