The strongest predictor of amino acid composition is the GC-content of the organism's genome<ref name="tekala-genomes">PMID: 12384285</ref>.

Thermophiles have more glutamic acid (with reduction in glutamine), and more lysine and arginine. This likely relates to the larger number of [[salt bridges]] in proteins of thermophiles, believe to contribute to thermostability. | Thermophiles have more glutamic acid (with reduction in glutamine), and more lysine and arginine <ref name="tekala-genomes" />.
