The search can be performed a pairwise fashion (input 2 domain identifiers and the system will pull back just the interactions between these two domains) or singly (input just one domain identifier and the system will pull back all partners). Input either a
SCOP identifier (
e.g. "a.2.7.1" for family level interactions or "a.2.7" for superfamily level interactions), a
CATH identifier (
e.g. "1.10.540.10.2" for sequence family level interactions or "1.10.540.10" for superfamily level interactions) or a
Pfam identifier (
e.g. "PF02629"). Both domains have to be from the same domain classification system
e.g. the input can not be one SCOP domain and one Pfam domain.
