  1. Mes stands for amino acid composition of mesophilic proteins, t_arc for amino acid composition of thermophilic archaeal proteins and t_eu for amino acid composition of thermophilic eubacterial proteins. HA stands for exposed alpha helices, Ha for non exposed alpha helices, EA for exposed beta strands, Ea for non exposed beta strands, CA for exposed coil and Ca for non exposed coil. The third letter is the standard code for amino acids. Values in bold significantly differ (P < 0.01) between thermophilic and mesophilic proteins.
