Welcome to the PDBbind-CN Database!
Introduction. The aim of the PDBbind database is to provide a comprehensive collection of the experimentally measured binding affinity data for all types of biomolecular complexes deposited in the Protein Data Bank (PDB). It thus provides an essential linkage between energetic and structural information of these complexes, which may be helpful for various studies on molecular recognition occurred in biological systems.
The PDBbind database was orginally developed by Prof. Shaomeng Wang's group (http://sw16.im.med.umich.edu) at the University of Michigan in USA, which was first released to the public in May, 2004. This database is now maintained and further developed at this web site, i.e. PDBbind-CN, by Prof. Renxiao Wang's group (http://www.sioc-ccbg.ac.cn) at the Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences in China under a mutual agreement with the University of Michigan. All registered users of the original PDBbind database have been granted access to the PDBbind-CN web site as well.
Current release. The PDBbind database is updated on an annual base to keep up with the growth of the Protein Data Bank. The current release, i.e. version 2013, is based on the contents of Protein Data Bank officially released on Jan 1st, 2013. This version provides binding affinity data and structural information for a total of 10,776 biomolecular complexes, including protein-ligand (8302), nucleic acid-ligand (83), protein-nucleic acid (587), and protein-protein complexes (1804), which is the largest collection of this kind so far. Binding data included in version 2013 have increased by 16% as compared to version 2012. All of these data are collected from >24,000 original references by ourselves. They all have been double-checked to ensure that they match the complex structures in the Protein Data Bank. Moreover, a "refined set" and a "core set" are compiled as high-quality data sets of protein-ligand complexes for docking/scoring studies.
