Abstract

DNA-damage recognition in the nucleotide excision repair (NER) cascade is a complex process, operating on a wide variety of damages. UvrB is the central component in prokaryotic NER, directly involved in DNA-damage recognition and guiding the DNA through repair synthesis. We report the first structure of a UvrB-double-stranded DNA complex, providing insights into the mechanism by which UvrB binds DNA, leading to formation of the preincision complex. One DNA strand, containing a 3' overhang, threads behind a {beta}-hairpin motif of UvrB, indicating that this motif inserts between the strands of the double helix, thereby locking down either the damaged or undamaged strand. The nucleotide directly behind the {beta}-hairpin is flipped out and inserted into a small, highly conserved pocket in UvrB.

Structural Basis for the Methylation State-Specific Recognition of Histone H4-K20 by 53BP1 and Crb2 in DNA Repair

Journal Article Botuyan,M. ; Lee, J. ; Ward, I. ; ... - Cell

Histone lysine methylation has been linked to the recruitment of mammalian DNA repair factor 53BP1 and putative fission yeast homolog Crb2 to DNA double-strand breaks (DSBs), but how histone recognition is achieved has not been established. Here we demonstrate that this link occurs through direct binding of 53BP1 and Crb2 to histone H4. Using X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy, we show that, despite low amino acid sequence conservation, both 53BP1 and Crb2 contain tandem tudor domains that interact with histone H4 specifically dimethylated at Lys20 (H4-K20me2). The structure of 53BP1/H4-K20me2 complex uncovers a unique five-residue 53BP1 bindingmore »« less

Structural Basis for Nick Recognition by a Minimal Pluripotent DNA Ligase

Journal Article Nair,P. ; Nandakumar, J. ; Smith, P. ; ... - Nature Structural and Molecular Biology

Chlorella virus DNA ligase, the smallest eukaryotic ligase known, has pluripotent biological activity and an intrinsic nick-sensing function, despite having none of the accessory domains found in cellular ligases. A 2.3-{angstrom} crystal structure of the Chlorella virus ligase-AMP intermediate bound to duplex DNA containing a 3'-OH-5'-PO{sub 4} nick reveals a new mode of DNA envelopment, in which a short surface loop emanating from the OB domain forms a {beta}-hairpin 'latch' that inserts into the DNA major groove flanking the nick. A network of interactions with the 3'-OH and 5'-PO{sub 4} termini in the active site illuminates the DNA adenylylation mechanismmore »« less

Structural Basis for DNA Recognition by FoxO1 and Its Regulation by Posttranslational Modification

Journal Article Brent,M. ; Anand, R. ; Marmorstein, R. - Structure

FoxO transcription factors regulate the transcription of genes that control metabolism, cellular proliferation, stress tolerance, and possibly life span. A number of posttranslational modifications within the forkhead DNA-binding domain regulate FoxO-mediated transcription. We describe the crystal structures of FoxO1 bound to three different DNA elements and measure the change in FoxO1-DNA affinity with acetylation and phosphorylation. The structures reveal additional contacts and increased DNA distortion for the highest affinity DNA site. The flexible wing 2 region of the forkhead domain was not observed in the structures but is necessary for DNA binding, and we show that p300 acetylation in wingmore »« less

Structural Basis for Dimerization in DNA Recognition by Ga14

Journal Article Hong,M. ; Fitzgerald, M. ; Harper, S. ; ... - Structure

Gal4 is a Zn2Cys6 binuclear cluster containing transcription factor that binds DNA as a homodimer and can activate transcription by interacting with the mutant Gal11P protein. Although structures have been reported of the Gal4 dimerization domain and the binuclear cluster domain bound to DNA as a dimer, the structure of the 'complete' Gal4 dimer bound to DNA has not previously been described. Here we report the structure of a complete Gal4 dimer bound to DNA and additional biochemical studies to address the molecular basis for Gal4 dimerization in DNA binding. We find that Gal4 dimerization on DNA is mediated bymore »« less
