2.4Spin labeled DNA ‐ structure, dynamics and DNA sequence analysis The major challenge in probingDNAstructure and conformation was introducing the probe at sensitive sites (ie.,purineor pyrimidine bases) which sense local structure, global motion, DNA wobbling, etc. A selected sample of a range...
After providing an aqueous solution containing a nucleic acid, heating the aqueous solution to cleave the nucleic acid; cooling the aqueous solution and adding a base-specific labeling molecule having available hydrogen bonds to the aqueous solution, the base-specific labeling molecules bond to the ...
2i). In the AAG–NCP–30AP structure, Y127 and Y159 interact with the AP site through hydrogen bonds (Fig. 2e, h), whereas the interaction between Y159 and the AP site is absent in the previously reported crystal structure, likely due to the lack of a hydroxyl group in pyrrolidine....
1d). Specific chemical interactions (for example, hydrogen bonds) depend on both location and orientation5. DeepPBS learns how the geometric orientation of the sym-helix points is associated with the orientations and chemistry of neighboring protein residues. Four distinct bipartite convolutions are ...
GQ is a non-canonical four-stranded helix composed of four guanine planar G-tetrads stabilized by Hoogsteen hydrogen bonds [125]; GQ aptamers can self-assemble and are very stable, and recognition of their targets can cause conformational changes [126]. The guanine of the fluorophore-labeled ...
In this sensor, the immobilized DNA probes bind to the introduced fluorescence-labeled Thymine (T)-rich DNA structure. The working principle of the system utilizes the ability of the heavy metals to interact with the thymine bases and to form the T-Heavy metal-T complex that creates a ...
The structure of DNA double helixDNA Directionality DNA backbone is formed by phosphodiester bond between the 5’ phosphate- and 3’ hydroxyl-groups of adjacent nucleotides; DNA double helix is stabilized by hydrogen bonds between the bases, and is antiparallel....
Figure 3. DNA has (a) a double helix structure and (b) phosphodiester bonds; the dotted lines between Thymine and Adenine and Guanine and Cytosine represent hydrogen bonds. The (c) major and minor grooves are binding sites for DNA binding proteins during processes such as transcription (the ...
