Table 1. Average values of the total number of cavities and the total cavity volume in protein tertiary structures and interfaces.
| Ter_strb | Interface | ||||
| Monomer | Homodimer | Overall | Inter_H | Inter_C | |
| No. of cavities | 15 (12.6) | 15.8 (14.9) | 15.5 (13.9) | 5.0 (4.5) | 2.4 (2.1) |
| Normalized no.a | 15 (6) | 15 (6) | 15 (6) | 25 (14) | 24 (17) |
| Total Cavity volume (Å3) | 455 (455) | 512 (561) | 486 (517) | 324 (498) | 97 (127) |
| Normalized volumea | 457 (247) | 485 (244) | 473 (245) | 1585 (1439) | 970 (1034) |
The standard deviations are in parentheses.
a
Number or volume (given in the previous row) per 2000 atoms. The volume of a 2,000 atom protein is about 49,000 Å3.
b
As the values obtained from the individual subunits of the monomer and homodimer datasets gave similar values, these were merged to get the ‘Overall’ value.
