Surface representation of the Haliangium ochraceum bacterial microcompartment (BMC) shell. Three types of protein shapes are visible (pentamers in yellow, hexamers in blue, and trimers in green).
Cheryl Kerfeld and Markus Sutter remove a puck containing crystallized proteins at Berkeley Lab's Advanced Light Source. They showed for the first time an intact bacterial microcompartment (BMC) shell, providing clues about its structure and assembly.
