We used a series of dATP and dGTP analogues to determine how DNA polymerase I from Bacillus stearothermophilus (BF), a prototypical A family polymerase, uses N-1, N(2), N-3, and N(6) of purine dNTPs to differentiate between right and wrong nucleotide

Steady-state and pre-steady-state kinetic constants were determined for reverse transcriptase catalyzed incorporation of nucleotides and nucleotide analogues into defined-sequence DNA primed-RNA templates. 3'-Azido-3'-deoxythymidine 5'-triphosphate (AZTTP) was almost as efficient a substrate (kcat/Km) as dTTP for the enzyme. In contrast, the
