Mean proportion of homologous nucleotide and amino acid sites within six SET genes and proteins common to seven S. aureus strainsa
| Gene | Inferred amino acid length in strain COL | Proportion of homologous nucleotide sitesb (mean ± SE) | Proportion of homologous amino acid sitesc (mean ± SE) |
|---|---|---|---|
| set1 | 233 | 0.81 ± 0.01 | 0.77 ± 0.02 |
| set2 | 239 | 0.95 ± 0.01 | 0.94 ± 0.01 |
| set3 | 243 | 0.95 ± 0.01 | 0.93 ± 0.01 |
| set9 | 359 | 0.92 ± 0.01 | 0.87 ± 0.01 |
| set10 | 262 | 0.95 ± 0.01 | 0.92 ± 0.01 |
| set11 | 246 | 0.89 ± 0.01 | 0.83 ± 0.02 |
a
S. aureus strains analyzed were 8325, Sanger MSSA, Sanger MRSA, N315, Mu50, COL, and MW2.
b
Mean proportion of homologous nucleotide sites = 1 − mean p-distance (in nucleotides). p-distance is the proportion (p) of nucleotide sites at which the sequences compared are different. The standard error was calculated by the bootstrap method.
c
Mean proportion of homologous amino acid sites = 1 − mean p-distance (in amino acids). The p-distance is the proportion (p) of amino acid sites at which the sequences compared are different. The standard error was calculated by the bootstrap method.
