Protein shape modulates crowding effects [Chemistry]

Protein−protein interactions are usually studied in dilute buffered solutions with macromolecule concentrations of <10 g/L. In cells, however, the macromolecule concentration can exceed 300 g/L, resulting in nonspecific interactions between macromolecules. These interactions can be divided into hard-core steric repulsions and "soft" chemical interactions. Here, we test a hypothesis from...
