The URLs for ftp/rsync services have been changed as follows. The previous URLs are still available for a while. - pdb.protein.osaka-u.ac.jp -> ftp.pdbj.org - snapshots.pdbj.org -> snapshots.pdbj.org The ftp command will connect to an anonymous ftp ...

Chemical shift

[Chemical Shift] NMR chemical shift file is mandatory when submitting NMR entries to the PDB after December 6, 2010. Deposition systems support the deposition of chemical shift data in NMR-STAR (V3.1) format and perform checks to confirm the ...

NMR restraints

[NMR restraints] NMR restraints file is required to deposit NMR structures after February 1, 2008. (version 1) There is no restriction on the format for the NMR restrains data. (Output format of Discover, Emboss, CYANA or X-PLOR is recommended) The ...

Structure factors

[Structure factors] Structure factors amplitudes/intensities in mmCIF format Structure factors file is required to deposit X-ray diffraction structures after February 1, 2008. For descriptions and examples of specific tokens, please refer to the ...

The Number of Equivalent Residues

[NER] NER stands for the Number of Equivalent Residues [1] is an empirical measure of the similarity of two protein structures. The NER superposition corresponds to the rotation and translation that maximizes the NER score. The NER score is bounded ...

ASH

Dear ASH User, As of February 2024, the laboratory of Genome Informatics, headed by Daron Standley, has suspended the operation of the ASH web service. The main reason for the suspension is a lack of IT personnel needed to perform security and data ...

structural genomics

Structural Genomics (SG) refers to the structural determination of all the proteins in a particular genome. More generally, SG has come to mean the effort to solve a representative set of protein structures, from which models of all proteins can be built ...

BMRB

https://bmrbdep.pdbj.org/index_en.html BMRB (Biological Magnetic Resonance Data Bank) is a database for NMR data of peptides, proteins, and nucleic acids, managed by the BioMagResBank at the University of Connecticut, USA. This website is maintained by ...

Spanner

URL: https://pdbj.org//spanner/ Spanner is a structural homology modeling program―that is, it threads a specific amino-acid sequence onto a specific PDB structure, patching up the gaps as best it can. To create a model, you must provide a template ...

sequence-representative

Sequence representative lists are generated by first computing BLAST scores for all pairs of structures. The pairs which score above a certain threshold (Sequence identity30% and E-value0.1) arelinked. The set is first clustered using single-linkage ...

NER

[NER] NER stands for the Number of Equivalent Residues [1] is an empirical measure of the similarity of two protein structures. The NER superposition corresponds to the rotation and translation that maximizes the NER score. The NER score is bounded ...

RMSD

RMSD stands for root mean square deviation. It is a commonly used measure of dissimilarity or error in protein structure. For two sets of points and a mapping between those points the RMSD is defined to be the square-root of the average of the squared ...

alignment

[Alignment] In bioinformatics, alignment refers to a mapping betweenequivalentamino acids (in the case of proteins) or nuceotides (in the case of DNA or RNA). In the case of proteins, we usually consider two basic types of alignment, sequence alignment ...

structural superposition

[Structural Superposition] The term structural superposition refers to rotations and translations performed on one molecular structure to make it match another structure or structures. Inherent in the definition of structural superposition is an assumed ...

PDB ID

[PDB ID] A PDB ID is a unique 4-character code for each entry in the Protein Data Bank. The first character must be a number between 1 and 9, and the remaining three characters can be letters or numbers.

BLAST

BLAST stands for Basic Alignment Search Tool. Because of its speed and the reliability, BLAST is a very widely used program for sequence alignment. The statistical significance of a BLAST alignment is given by its expectation value or E-value. The E-value ...

PDBML-extatom

PDBML-extatom files contain atomic coordinates in a "simplified" format. The XML schema for PDBML-extatom format is provided at: - https://pdbj.org//schema/pdbx-v40-ext.xsd And can also be viewed using our interactive XML viewer. In the canonical PDBML ...

SeSAW Tutorial

In this tutorial, we provide explanation about the SeSAW, one of the service of PDBj. See also the SeSAW documentation about basic things such as used technique. - Submitting PDB entries to SeSAW - Submitting structures to SeSAW - Experimental ...

structural domain

A structural domain is a level of organization that is intermediate between secondary structure and tertiary structure. For single domain structures, a structural domain can be thought of as being equivalent to the tertiary structure, with the caveat that ...

Functional annotation example

[Functional Annotation of] 1uan 1uan (TT1542 from Thermus thermophilus HB8) is a structural genomics (SG) target solved as part of the Protein 3000 project in Japan [1]. At the time the structure was solved, there were no PDB entries with significant ...
