Average values of the total number of cavities and the total cavity volume in protein tertiary structures and interfaces.

The standard deviations are in parentheses.aNumber or volume (given in the previous row) per 2000 atoms. The volume of a 2,000 atom protein is about 49,000 ?3.bAs the values obtained from the individual subunits of the monomer and homodimer datasets gave similar values, these were merged to get the ��Overall�� value.
