Discrimination by DNA polymerases controls the fidelity of DNA replication, and reduced fidelity results in mutations essential in the etiology of cancer. Polymerase discrimination operates at both dNTP insertion and subsequent elongation steps, and involves several energetic and structural factors that are as yet incompletely understood. While base pairing interactions have been studied extensively, substantially less is known about the role of sugar structure and conformation for polymerase incorporation and extension. In these studies we examined, systematically, the role of sugar structure and conformation on polymerase selection of the dNTP for insertion and polymerase elongation. To accomplish these goals, we …
