From: Characteristics and clustering of human ribosomal protein genes
Hierarchical clustering of ribosomal protein (RP) genes by amino acid composition. The black regions represent low frequencies of encoding of the amino acid (column) by that gene (row) whereas the red regions represent high frequencies of encoding. (F: Phenylalanine, L: Leucine, I: Isoleucine, M: Methionine, V: Valine, P: Proline, T: Threonine, A: Alanine, Y: Tyrosine, H: Histidine, Q: Glutamine, N: Asparagine, K: Lysine, D: Aspartic acid, E: Glutamic acid, C: Cysteine, W: Tryptophan, R: Arginine, S: Serine, G: Glycine)
