  1. Alternative amino acid residues are in brackets. 'X' is any residue. 1 – residue present in three or more of the six aligned sequences; 2 – residue present in four or more of the six aligned sequences; 3 – residue in contact with nucleic acid template, dNTP or Mg2+ ; 4 – point mutations of this residue abolish catalytic activity.
