biotechnology DNA polymerase plays prominent roles in numerous biotechnologies. The use of diphosphate substrates has the potential to make practical the incorporation of expensive analogs, such as isotopically labeled or chemically modified nucleotides, eliminating the need for challenging triphosphate syntheses. This feature of DNA polymerases may also provide a method for detecting nucleotides used in high-throughput DNA sequencing Thermus aquaticus

a 2'-deoxyribonucleoside 5'-triphosphate + DNAn Thermus aquaticus DNA replication can be accomplished using dNDPs as substrates. In thermophiles, genome replication may be less sensitive to the energy charge of the cell than in mesophiles because thermostable polymerases can accept the diphosphorylated as well as the triphosphorylated substrates. DNA replication is thus less affected by the intracellular ATP/ADP ratio, and the relatively high efficiency with which DNA is synthesized at elevated temperatures suggests that thermophiles may be able to dispense with the triphosphorylated substrates entirely diphosphate + DNAn+1
