sunid (This SCOP unique identifier consists of 5 digits, e.g. 49507 for the protein domain Plastocyanin. It uniquely identifies any entries in the SCOP hierarchy).
sccs (This set of concise classification strings is associated with the most relevant hierarchical levels. For example in d.126.1.1., d stands for the class, 126 for the fold and the remaining two 1 for superfamily and family).
The keyword search can either be performed for protein domain, family,
superfamily, fold, class names or for the comments.
Protein domain, family, superfamily, fold, class search: Search for hemoglobin gives only results
for Hemoglobin, whereas due to the usage of the wildcard sign
% search for %hemoglobin% gives also Truncated
hemoglobin or Leghemoglobin, for example.
Boolean keyword combinations are not possible.
You can, however, search for strings that correspond exactly to SCOP
descriptions, such as 70 KDa soluble lytic transglycosylase (SLT70),
superhelical domain or 4-helical cytokines. You will
get no hit for 4-helical cytokine because of the missing
s at the end. So, if you do not know the SCOP description exactly
use wildcards such as %transglycosylase% or %helical%
Comment search: If you are interested in all protein domains complexed with
Mg, you can use the search string %complexed with% Mg% and the
comments only option selected. The % wildcard after
with ensures that you will get a hit, even if the corresponding
comment line includes several ligands with Mg not mentioned in the first
