Serpins are a group of proteins with similar structures that were first identified as a set of proteins able to inhibit proteases. This volume in the Methods in Enzymology series comprehensively covers this topic. With an international board of authors, this volume covers subjects such as Crystallography of serpins and serpin complexes, Serpins as hormone transporters, and Production of serpins using cell free systems.
