There are three major reasons why the insertion of disulfide bridges into a protein is important:

  • To stabilize proteins against thermal denaturation - an approach often used in industrial biotechnology.
  • To study the internal dynamics of a protein by blocking an open / closed or active / inactive state, this approach has made it possible to study several molecular mechanisms such as the movement of transmembrane helices in response to a stimulus.
  • To link two domains or two proteins to one another, an approach often used to stabilize variable antibody fragments and for our projects on coagulation factors.
