Crystal Structure of a DinB Family Error Prone DNA Polymerase from Sulfolobus solfataricus
Overview
A new group of error-prone DNA polymerases overcomes the blockage posed to normal DNA replication by damaged template bases, suggesting an active site with a loose, flexible pocket that accommodates aberrant DNA structures. We have determined a 2.8 A resolution crystal structure of the Sulfolobus solfataricus Dbh protein, a DNA translesion polymerase closely related to Escherichia coli DNA polymerase IV and human polymerase kappa. A high error rate is observed for the Dbh polymerase in a range of 10(-2)-10(-3) for all 12 base substitution mispairs. The crystal structure of Dbh reveals an overall architecture resembling other DNA polymerases but has unique features that are likely to contribute to error-prone synthesis, including -1 frameshifting mutations.
