Figure 6From: The oligodeoxynucleotide sequences corresponding to never-expressed peptide motifs are mainly located in the non-coding strandEffect of amino acid composition on pentapeptide frequency in the universal proteome. Frequency of: A) pentapeptides never-expressed in the universal proteome, and B) their inverse sequences. Frequency of: C) pentapeptides with 2500 occurrences in the proteome, and D) their inverse sequences.Back to article page
