The photo-control of protein activity can often be achieved via the photo-control of protein structure. Intramolecular cross-linkers that change length upon photoisomerization provide a means to photo-control protein structure by linking to pairs of Cys residues in a protein sequence. In this protocol, we describe general methods for introducing intramolecular cross-linkers, both UV light switchable and red-light switchable, under either denaturing or native conditions.
