Key points from article :
University of North Carolina scientists are engineering proteins with functionality that nothing else is capable of doing.
Structure of a protein determines its function so have to learn how to design new structures.
Team developed a computer design strategy called SEWING – Structure Extension With Native-substructure Graphs – which digitally chopped up naturally occurring proteins.
21 new proteins produced in the lab.
Could help design new cellular machines needed to understand and battle diseases.
The study was published in the Science journal.
