E+K/Q+H values for the proteomes of 28 organisms versus optimal growth temperature (OGT). E+K/Q+H ratio = %E (Glu) + %K (Lys) divided by %H (His) + %Q (Gln) in the same proteome. Amongst HT, OGT ranges from 80-100°C, in T from 60-65°C and in M from 24-37°C. E+K/Q+H ratio discriminated hyperthermophilic, thermophlllc and mesophilic lifestyles. The identification of the organisms is in Table 2.
