Nuclear magnetic resonance spectroscopy of proteins
Nuclear magnetic resonance spectroscopy of proteins is a field of structural biology in which NMR spectroscopy is used to obtain information about the structure and dynamics of proteins, and also nucleic acids, and their complexes. The field was pioneered by Richard R. Ernst and Kurt Wüthrich at the ETH, and by Ad Bax, Marius Clore, and Angela Gronenborn at the NIH, among others. Structure d…

What is the Protein Data Bank?
The Protein Data Bank (PDB) was born in the early 1970s, when it became clear that there was much to learn from comparative analysis of protein structures. The PDB archives now contain the experimentally determined three-dimensional coordinates for more than 32 000 macromolecules.
What is a protein database and how to create one?
A protein database is one or more datasets about proteins, which could include a protein’s amino acid sequence, conformation, structure, and features such as active sites. Protein databases are compiled by the translation of DNA sequences from different gene databases and include structural information.
What is the RCSB protein data bank?
This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. As a member of the wwPDB, the RCSB PDB curates and annotates PDB data.
How many proteins are annotated in UniProtKB?
A total of 868 (34.53%) protein structures satisfy the two criteria, whereas 520 structures remained as proteins of unknown functions. Another 1097 proteins have equivalents that are also annotated as uncharacterized proteins in the UniProtKB, and only 64 proteins have no UniProtKB equivalents.
What is Protein Data Bank in bioinformatics?
Protein Data Bank (PDB) is the single worldwide archive of structural data of biological macromolecules. It includes data obtained by X-ray crystallography and nuclear magnetic resonance (NMR) spectrometry submitted by biologists and biochemists from all over the world.
What is the use of Protein Data Bank?
Through an internet information portal and downloadable data archive, the PDB provides access to 3D structure data for large biological molecules (proteins, DNA, and RNA). These are the molecules of life, found in all organisms on the planet.
What is Protein Data Bank Slideshare?
The Protein Data Bank (PDB) is a database for the three-dimensional structural data of large biological molecules, such as proteins and nucleic acids. This presentation deals with what, why, how, where and who of PDB.
Who maintains the Protein Data Bank?
The PDB is overseen by an organization called the Worldwide Protein Data Bank, wwPDB. The PDB is a key in areas of structural biology, such as structural genomics. Most major scientific journals and some funding agencies now require scientists to submit their structure data to the PDB.
What is in a PDB file?
A program database file (extension . pdb) is a binary file that contains type and symbolic debugging information gathered over the course of compiling and linking the project. A PDB file is created when you compile a C/C++ program with /ZI or /Zi or a Visual Basic, Visual C#, or JScript program with the /debug option.
Why is PDB ID important?
Relevance of Identifiers in PDB Exploration In order to explore the structure and analyze molecular interactions in atomic detail, the locations of each atom in the PDB must be uniquely assigned. Various identifiers are used to specifically indicate one atom or groups of atoms.
Who runs the PDB?
Led by Helen M. Berman, the Research Collaboratory for Structural Bioinformatics (RCSB) became responsible for the management of the PDB in 1998 in response to an RFP and a lengthy review process.
Where is the Protein Data Bank?
The Protein Data Bank (PDB; http://www.rcsb.org/pdb/ ) is the single worldwide archive of structural data of biological macromolecules.

What is PDB code?
PDB identification code. Every molecular model (atomic coordinate file) in the Protein Data Bank (PDB) has a unique accession or identification code. These codes are always 4 characters in length.
What is PDB 101?
PDB-101 is an online portal for teachers, students, and the general public to promote exploration in the world of proteins and nucleic acids.
What is a PDB?

Presents short accounts on selected molecules from the Protein Data Bank. Access materials that promote exploration in the world of proteins and nucleic acids.
What is validation report?
Validation reports contain an assessment of the quality of a structure and highlight specific concerns by considering the coordinates of the model, the experimental data and the fit between the two. Easily interpretable summary information that compares the quality of a model with that of other models in the archive will help users of PDB data to critically assess archived entries and to select the most appropriate structural models for their needs. These reports are developed using the recommendations of the wwPDB Validation Task Forces.
Importance of Protein Databases
Primary Databases of Protein
- The PRIMARY databases hold the experimentally determined protein sequences inferred from the conceptual translation of the nucleotide sequences. This, of course, is not experimentally derived information, but has arisen as a result of interpretation of the nucleotide sequence information and consequently must be treated as potentially containing misinterpreted information. There is …
Secondary Databases of Protein
- The secondary databases are so termed because they contain the results of analysis of the sequences held in primary databases. Many secondary protein databases are the result of looking for features that relate different proteins. Some commonly used secondary databases of sequence and structure are as follows: a. PROSITE: 1. A set of databases collects together patte…
