Table 4 Normalized relative occurrences. Normalized relative occurrences of all amino acids at the different positions. For the normalization we used the coefficient of each observed occurrence and the natural occurrence for each amino acid at each position. Highlighted in bold are the most probable amino acid (H > 1) occurring at the four positions.

From: Statistically significant dependence of the Xaa-Pro peptide bond conformation on secondary structure and amino acid sequence
