A study has found that an ancient protein motif that binds to nucleic acids is functionally "ambidextrous." This means that the motif can interact with both natural and mirror-image nucleic acids, an ...

Protein problem: Researchers challenge fundamental assumption in evolutionary biochemistry
How did life originate? Ancient proteins may hold important clues. Every organism on Earth is made up of proteins. Although all organisms—even single-celled ones—have complex protein structures now, ...
Researchers found a rare example of an ancient protein that can still function in a molecular mirror world – offering new clues about the evolutionary history of proteins that bind to nucleic acids.
