The crystal structures of the Klenow fragment of the Thermus aquaticus DNA polymerase I (Klentaq1) complexed with four deoxyribonucleoside triphosphates (dNTP) have been determined to 2.5 A resolution. The dNTPs bind adjacent to the O helix of Klentaq1. The triphosphate moieties are at nearly identical positions in all four complexes and are anchored by three positively charged residues, Arg659, Lys663, and Arg587, and by two polar residues, His639 and Gln613 ...
