Type II conserved positions.

1Amino acid positions are numbered according to T. thermophilus EFG-2 structure 1WDT. An alternative numeration (EFG-1 of T. thermophilus) is given in brackets.2Three most represented amino acids, in a single letter code separated by commas. Amino acid shown with small letter when the conservation is 3Percentage of conservation corresponding to the amino acids found in these positions.4Only those positions are shown where the difference in conservation of the most conserved amino acid exceeds 25% between the EFG I and EFG II subfamilies.
