Aptamer applications

Structures

This page provides a summary of the methods used for structure determination and phasing in RNA aptamer structure research. Additionally, we provide a comprehensive list of all the structured RNA aptamer included in this collection, along with their respective Protein Data Bank (PDB) entries.


Statistical information

A statistical analysis has been conducted on the structural determination and phase elucidation of RNA aptamers. Upper left figure: A statistical summary of structural elucidation methods for RNA aptamers, including X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and cryo-electron microscopy (cryo-EM). Upper right figure: A statistical summary of solutions to phase problems generated by X-ray structural elucidation, such as Molecular Replacement (MR). Lower left figure: A statistical summary of phase problem solutions for aptamers targeting small molecules. Lower right figure: A statistical summary of phase problem solutions for aptamers targeting proteins and nucleic acids.
