1、Incorporation of multiple sequential pseudothymidines by DNA polymerases and their impact on DNA duplex structure
Stephanie A Havemann , Shuichi Hoshika, Daniel Hutter, Steven A Benner

Abstract：Thermal denaturation and circular dichroism studies suggested that multiple (up to 12), sequential pseudothymidines, a representative C-glycoside, do not perturb the structure of a representative DNA duplex. Further, various Family A and B DNA polymerases were found to extend a primer by incorporating four sequential pseudothymidine triphosphates, and then continue the extension to generate full-length product. Detailed studies showed that Taq polymerase incorporated up to five sequential C-glycosides, but not more. These results constrain architectures for sequencing, quantitating, and analyzing DNA analogs that exploit C-glycosides, and define better the challenge of creating a synthetic biology using these with natural polymerases.

2、An in vitro screening technique for DNA polymerases that can incorporate modified nucleotides. Pseudo-thymidine as a substrate for thermostable polymerases
S Lutz , P Burgstaller, S A Benner

Abstract：DNA polymerases are desired that incorporate modified nucleotides into DNA with diminished pausing, premature termination and infidelity. Reported here is a simple in vitro assay to screen for DNA polymerases that accept modified nucleotides based on a set of primer extension reactions. In combination with the scintillation proximity assay (SPA[trade]), this allows rapid and simple screening of enzymes for their ability to elongate oligonucleotides in the presence of unnatural nucleotides. A proof of the concept is obtained using pseudo-thymidine (psiT), the C-nucleoside analog of thymidine, as the unnatural substrate. The conformational properties of psiT arising from the carbon-carbon bond between the sugar and the base make it an interesting probe for the importance of conformational restraints in the active site of polymerases during primer elongation. From a pool of commercially available thermostable polymerases, the assay identified Taq DNA polymerase as the most suitable enzyme for the PCR amplification of oligonucleotides containing psiT. Subsequent experiments analyzing PCR performance and fidelity of Taq DNA polymerase acting on psiT are presented. This is the first time that PCR has been performed with a C-nucleoside.
