SIZE AND FUNCTION OF CAPSID. “The capsid size has likely evolved to accommodate the size of the material to be packaged as T. maritima encapsulins package small ferritin-like proteins inside a particle with an inner volume of 4.18×10(6) Å3 while Phage G requires a much larger capsid (inner volume=1.87×10(9) Å3) to package its 670 kb chromosome.”
