From: Measuring the functional sequence complexity of proteins
Measure of FSC/site for ubiquitin. The plot shows how the FSC value varies between sites for a protein family of ubiquitin. At site 37, all 20 amino acids are observed, with a relatively high Fit value of 2.9. It indicates that measure of FSC also depends on the number of amino acid types observed as well as the distribution of frequencies of each type.
