Crystal structure of a S-diastereomer analogue of the spore photoproduct in complex with fragment DNA polymerase I from Bacillus stearothermophilusCrystal structure of a S-diastereomer analogue of the spore photoproduct in complex with fragment DNA polymerase I from Bacillus stearothermophilus
Structural highlights
Publication Abstract from PubMedUV light is one of the major causes of DNA damage. In spore DNA, due to an unusual packing of the genetic material, a special spore photoproduct lesion (SP lesion) is formed, which is repaired by the enzyme spore photoproduct lyase (Spl), a radical S-adenosylmethionine (SAM) enzyme. We report here the synthesis and DNA incorporation of a DNA SP lesion analogue lacking the phosphodiester backbone. The oligonucleotides were used for repair studies and they were cocrystallized with a polymerase enzyme as a template to clarify the configuration of the SP lesion and to provide information about the base-pairing properties of the lesion. The structural analysis together with repair studies allowed us to clarify the identity of the preferentially repaired lesion diastereoisomer. Crystal structures and repair studies reveal the identity and the base-pairing properties of the UV-induced spore photoproduct DNA lesion.,Heil K, Kneuttinger AC, Schneider S, Lischke U, Carell T Chemistry. 2011 Aug 22;17(35):9651-7. doi: 10.1002/chem.201100177.
