FEN Nucleases: Bind, Bend, Fray, Cut
In this issue, Orans et al. (2011) and Tsutakawa et al. (2011) report exciting insights into the molecular principles governing diverse endo- and exonucleolytic cleavage specificities of members of the RAD2/FEN superfamily of nucleases, which have critical roles in DNA replication and maintenance.
متن کاملFour p53 DNA-binding domain peptides bind natural p53-response elements and bend the DNA.
Recent structural studies of the minimal core DNA-binding domain of p53 (p53DBD) complexed to a single consensus pentamer sequence and of the isolated p53 tetramerization domain have provided valuable insights into their functions, but many questions about their interacting roles and synergism remain unanswered. To better understand these relationships, we have examined the binding of the p53DB...
متن کاملAccelerated Bend Minimization
We present an O(n) algorithm for minimizing the number of bends in an orthogonal drawing of a plane graph. It has been posed as a long standing open problem at Graph Drawing 2003, whether the bound of O(n7/4√logn) shown by Garg and Tamassia in 1996 could be improved. To answer this question, we show how to solve the uncapacitated min-cost flow problem on a planar bidirected graph with bounded c...
متن کاملBend into shape
Bacteria come in a variety of shapes, as most species elaborate on the ‘default’ sphere to resemble ovoids, rods, bend rods, spirals, branched filaments or other more complicated forms. How cells that are under considerable turgor pressure maintain a nonspherical shape is unclear, though it is known to depend on structural elements on either side of the cytoplasmic membrane: the murein (peptido...
متن کاملBend it like pollen
images inspired by the remarkable twists and turns in the shape of pollen grains from different plant species collected by the artist from specimens growing in the gardens' cornfield last summer. Kessler was awarded a three-year grant to work with Madeline Harley at the Micromorphology Unit at Kew. The remarkable shapes of pollen grains reveal important diagnostic features of plants used by sci...
