HomodimerDB
HomodimerDB is a database of all homodimeric protein structures in the
PDB database, pruned to be
non-redundant both in terms of structure and sequence.
Starting from the complete set of known
homodimer structures (all identical-sequence chains in the PDB that are in
contact), the database is built by clustering the set to a sequence identity
of 90%, then selecting only unique homodimer structures, as defined by
clustering using
US-align structural alignment. The
resulting data, therefore, non-redundantly includes all unique
sequence-structure combinations that constitute a homodimeric interaction in
the PDB.
