Figure 4From: A comparative study of ribosomal proteins: linkage between amino acid distribution and ribosomal assemblyProportion of Lysine residues correlates with average protein length but Arginine does not. Lysine (A) shows a highly significant negative correlation with protein length (Spearman’s rank correlation: ρ = −0.802, p=2.60x10-5), whereas Arginine (B) shows a weaker correlation with no statistical significance (ρ = −0.484, p=0.032).Back to article page
