2005年4月19日 · This data set includes a unique set of amphimorphic sequence, those that crystallize in two different conformations and serve to bridge the three structural phases. We have thus constructed a map of DNA structures that can be walked through in single nucleotide steps.

Structure of a B-DNA dodecamer: conformation and dynamics. The crystal structure of the synthetic DNA dodecamer d (CpGpCpGpApApTpTpCpGpCpG) has been refined to a residual error of R = 17.8% at 1.9-A resolution (two-sigma data). The molecule forms slightly more than one complete turn of right-handed double-stranded B helix.

2023年12月20日 · 输入DNA序列以及DNA结构类型，即可立刻返回产生的pdb结构，例如： 返回的结构用VMD查看： 地址： http://web.x3dna.org. 进入后，选Rebuilding - combination of A-, B-, or C-form DNA models。 之后可以输入DNA序列由几段构成，比如设了3，点next，若三段内容分别按下面这样设，那么DNA序列就是AAACCCCGGG，且其中AAA部分是A-DNA形式、CCCC部分是B-DNA形式、GGG部分是C-DNA形式。 提交之后，过一会儿（有可能时间挺长），看到下 …

RCSB Protein Data Bank (RCSB PDB) enables breakthroughs in science and education by providing access and tools for exploration, visualization, and analysis of: These data can be explored in context of external annotations providing a structural view of biology. 3D visualization for PDB structures and ligand binding sites.

DNAproDB is a database, structure processing pipeline, and visualization tool to analyze DNA-protein complexes. Search thousands of DNA-protein complex structures based on features of the DNA, protein or DNA-protein interactions. Visualize …

DNA is read-only memory, archived safely inside cells. Genetic information is stored in an orderly manner in strands of DNA. DNA is composed of a long linear strand of millions of nucleotides, and is most often found paired with a partner strand. These strands wrap around one another in the familiar double helix, as shown here.

2024年11月2日 · 蛋白质数据库核酸部分（Protein Data Bank of Nucleic Acids, PDB-NA）是生物信息学领域中一个重要的资源，专注于存储和提供核酸分子的三维结构数据。 该数据集由国际蛋白质数据库（Protein Data Bank, PDB）维护，自1971年创建以来，已成为研究核酸结构与功能的核 …

What is DNA? DNA is perfect for the storage and readout of genetic information. This information is stored in the sequence of Adenine, Thymine, Guanine, and Cytosine - also called A, T, G, and C. Each helix has a backbone made of alternating deoxyribose and phosphate groups.

DNA polymerase makes an accurate copy of the cell's genome. Taq DNA polymerase, with a short piece of DNA in magenta and green. DNA polymerase plays the central role in the processes of life. It carries the weighty responsibility of duplicating our genetic information.

可以使用下面方法简单的生成其螺旋结构的PDB文件。 1、打开下面链接. 2、在对话框中输入其序列，之后选择DNA的螺旋：A-DNA为右手螺旋，B-DNA右手螺旋，MD DNA是使用分子动力学优化的结构。 然后选择Submit Sequence 。 3、点击下图地方下载文件。 会生成自动碱基配对之后的DNA结构。 若只想要一条链，直接打开pdb文件，手动删除多余链即可。 4、若不知道具体序列，只想要一个随意的DNA的pdb结构，那么可以使用下面网页随机建立指定长度的DNA序列。 …
