Bonding Radii of 80S Ribosomes


THERE are now clear descriptions of the packing of ribosomes from two different nucleated organisms into two different crystal forms. One form, the chromatoid bodies of Entamoeba invadens, is a hexagonal array of helices1. The other form, found in mitotic cells of chilled chick embryos, consists of tightly packed layers of plane lattices2. At first sight there is no apparent relation between the packing of ribosomes within these two forms. We will show, however, that there is a way of looking at the bonds which these ribosomes form which closely relates one packing scheme to the other.
