Abstract excerpt
Ultraviolet-induced DNA damage poses a lethal block to replication. To understand the structural basis for this, we determined crystal structures of a replicative DNA polymerase from bacteriophage T7 in complex with nucleotide substrates and a DNA template containing a cis-syn cyclobutane pyrimidine dimer (CPD). When the 3' thymine is the templating base, the CPD is rotated out of the polymerase active site and...
