  1. t-tests of sequence percent compositions of mesophilc, thermophilic, and hyperthermophilic proteins Amino acids significantly over-represented in hyperthermophiles with respect to mesophiles are: Glu, Ile, Lys, Arg, and Val. Amino acids significantly under-represented in hyperthermophiles with respect to mesophiles are: Ala, Cys, Asp, His, Asn, Pro, Gln, Ser, Thr, and Trp. Amino acids significantly over-represented in thermophiles with respect to mesophiles are: Ala, Glu, Gly, Leu, Pro, Arg, and Val. Amino acids significantly under-represented in thermophiles with respect to mesophiles are: Cys, Asp, Lys, Met, Asn, Gln, Ser, and Thr. Amino acids significantly over-represented in hyperthermophiles with respect to thermophiles are: Glu, Ile, and Lys. Amino acids significantly under-represented in hyperthermophiles with respect to thermophiles are: Ala, Gly, His, Leu, Pro, Gln, Arg, and Thr. These statistics were tabulated from nonredundant sets of 184 hyperthermophilic structures (45419 residues), 162 thermophilic structures (41470 residues), and 1262 mesophilic structures (269799 residues).
