Table 3 Temperature adaptations of the dnaE-based groups

From: On the molecular mechanism of GC content variation among eubacterial genomes

  Total dnaE1|polV dnaE1|dnaE2 dnaE3|polV
Psychrotrophic 75 (100%) 34 (45.3%) 36 (48.0%) 5 (6.7%)
Mesophilic 116 (100%) 47 (40.5%) 31 (26.7%) 38 (32.8%)
Thermophilic 21 (100%) 6 (28.6%) 2 (9.5%) 13 (61.9%)

  1. Note: We classified bacteria as 'psychotropic' whose environmental temperature requirement < = 30°C, 'mesophilic' < = 45°C, and 'thermophilic' > = 75°C. The number of bacteria in each group is provided for each temperature obligation class, and their percentages in each class are given in parentheses.
