摘要
Interactions between proteins are important to understand but difficult to study. Conjugating a protein to a small artificial protease endows it with the ability to cut other proteins where it binds to them. Analysing the sites cut on the target proteins leads to new understanding of the structure of each complex. The binding of a factors to a common region on RNA polymerase provides an example.
