Functional role of a conserved aspartate in the hinge joining the M and N helices investigated. Aspartate in the hinge region is catalytically important and is required for dNTP binding and in the formation of a prepolymerase ternary complex

Recominant enzyme purified and biochemically characterised. Unable to discriminate against ddNTPs and is inhibited by these chain-terminating nucleotide analogues. Role of 9 invariant acidic residues in 5' nuclease domain evaluated. Acidic side chain neutralisation resulted in a >20-fold reduction in activity, with greatest reduction caused by neutralisation of Asp125, Asp148 and Asp150
