Abstract: The size dependent complexity of protein sequences in various families in the FSSP database is characterized by sequence entropy, sequence similarity and sequence identity. As the average length L f of sequences in the family increases, an increasing trend of the sequence entropy and a decreasing trend of the sequence similarity and sequence identity are found. As L f increases beyond 250, a saturation of the sequence entropy, the sequence similarity and the sequence identity is observed. Such a saturated behavior of complexity is attributed to the saturation of the probability P g of global (long-range) interactions in protein structures when L f >250. It is also found that the alphabet size of residue types describing the sequence diversity depends on the value of L f , and becomes saturated at 12.
