Location of the 5-mer sets selected for physico-chemical analyses along the distribution curve of pentapeptide frequencies in the universal proteome. UniRef100, the most comprehensive protein dataset available [[16–18], see also http://www.ebi.ac.uk/uniref/], was used. The arrows, lettered from b to k, indicate the frequencies of the different 5-mer sets corresponding, in the order, to 1, 4, 5, 50, 100, 341, 500, 1000, 1368 and 2500 occurrences and selected for physico-chemical analyses. A further set a, corresponding to the set of never-occurring pentapeptides, was also chosen.
