exists mainly in the nucleus and mitochondria of each cell in an organism. It consists of two long strands linked together in a structure resembling a ladder twisted into a spiral, called adouble helix.Each rung is made up of two chemical bases, callednucleotides,that are joined together by ...
The bases on each strand are joined to the bases on the other strand with hydrogen bonds, but different bases have different chemical structures. Cytosine and thymine (and uracil in RNA) are pyrimidines, containing one ring. Adenine and guanine are purines, containing two rings. The pyrimidine...

We have solved the 2.2 Å X-ray crystal structure of a complex of WP631 bound to [d(CGATCG)]2. We demonstrate, on a detailed molecular level, that the WP631 design strategy is a success. The structures of WP631 and two daunomycin molecules bound to [d(CGATCG)]2 provide the ...

Significant secondary chemical shifts indicate the presence of two separated α-helical regions. The C-terminal leucine zipper region forms a compact α-helix, while the N-terminal basic region exhibits conformational averaging with substantial α-helical content. Both helices lack stabilizing tertiary ...
There are two major classes of chemical probes of DNA structure: those that demonstrate no inherent base preference but are sensitive to DNA geometry, such as groove widths and chirality, and those that are base-specific, detecting bases in distorted regions of the helix. The former bind to DN...
A protein structural domain that binds DNA and RNA, and that is found most commonly in transcription factors. It consists of a helix–turn–helix structure of 60 amino acids. GAR domain A Gly- and Arg-rich motif that adopts a repeated β-turn structure. It is found most commonly in prote...
