From: Recognizing protein–protein interfaces with empirical potentials and reduced amino acid alphabets
Discrimination according to Protein Size. Discrimination power of the different amino acid alphabets for fold recognition as a function of protein length (number of amino acids). The corresponding energy functions are those derived for fold recognition, using the Monomeric Optimization Set. The mean number of decoys is shown vs. protein length (grey bars; righthand graduations).
