PDB-REPRDB Selection Criterion
Each representative is different from all other representatives in terms of either
a ) Sequence similarity (ID% =< threshold1)
ID%:
Percentage of identical amino-acid residues between corresponding residue pairs in the two compared sequences.
OR
b ) 3-dimensional structures similarity (MAXD >= threshold2)
MAXD:
Maximum 'Ca'-distance between the corresponding residue pairs in the two compared structures.
Threshold sequence identity
ID%		 Number of chains
