DNA polymerase recognition of 2'-deoxy-2'-fluoroarabinonucleoside 5'-triphosphates (2'F-araNTPs).

We examined the ability of 2'-deoxy-2'-fluroarabinonucleoside 5'-triphosphates (2'F-araNTPs) to serve as substrates of various DNA polymerases. In addition, we also examined the ability of these polymerases to accept DNA-FANA (2'-deoxy-2'-fluoroarabinonucleic acids) chimeras as template strands while synthesizing a DNA or FANA-DNA complementary strand. We provide preliminary data demonstrating that 2'F-araNTPs are indeed substrates of several DNA polymerases, and that FANA-DNA chimeric templates are generally well recognized by these polymerase enzymes.
