Method Using Voronoi volume calculations on RNA crystal structures, a self-consistent, universal set of atomic volumes was obtained. The atomic volumes obtained from this analysis are consistent across different RNA structures and packing environments.
Comments The solvent excluded volume is obtained by subtracting solvent volume from shell volume. This experimental value (0.592 mL/g) compares reasonably well with the value implied by solvent-excluded surface (0.627 mL/g) considering no effort was made to address the net charge of the molecule or electrostriction effects of the solvent on this calculation.
