The following Table shows the distribution of all the 426 protein chains in terms of SCOP classes. Majority of proteins have 'alpha/beta' class followed by 'all beta' and 'alpha+beta' class.
| Number of alpha proteins ( class a ) | 68 |
| Number of beta proteins (class b ) | 97 |
| Number of alpha/beta proteins (class c ) | 102 |
| Number of alpha+beta proteins (class d) | 86 |
| Number of multi-domain proteins (class e ) | 9 |
| Number of small proteins (class f ) | 2 |
| Number of coiled coil proteins (class g ) | 22 |
| Number of low resolution proteins (class h ) | 0 |
| Number of peptides (class i ) | 0 |
| Number of designed proteins (class j ) | 1 |
| Number of proteins having both a and b classes | 3 |
| Number of proteins having both a and c classes | 7 |
| Number of proteins having both a and d classes | 5 |
