Figure 2. Amino acid abundance.

Figure 2

The abundance of each amino acid in the proteome depends on several factors including codon degeneracy. Relative to its abundance in the human proteome (2,31%), cysteine is found most often (6,06%; a 2,62-fold increase) as a result of a missense mutation in cancer in the COSMIC database.
