  • As technology gets better, scientists can see more - in this case, they’ve been noticing that not all proteins have only one purpose, as previously believed.
  • Turns out that proteins can fold into different shapes depending on what they’re told to do.

  • Another shape allows it to become an antibiotic, and kill invasive bacteria.
