Abstract
Protein Science, the flagship journal of The Protein Society, serves an international forum for publishing original reports on all scientific aspects of protein molecules. The Journal publishes papers by leading scientists from all over the world that report on advances in the understanding of proteins in the broadest sense. Protein Science aims to unify this field by cutting across established disciplinary lines and focusing on “protein-centered” science.
