Since 2014, the PDB format was substituted as the standard PDB archive distribution by the PDBx/mmCIF file format (.cif). While PDB format contains a set of records identified by a keyword of up to six characters, the PDBx/mmCIF format uses a structure based on key and value, where the key is a name that identifies some feature and the value is ...
The file format initially used by the PDB was called the PDB file format. The original format was restricted by the width of computer punch cards to 80 characters per line. Around 1996, the "macromolecular Crystallographic Information file" format, mmCIF, which is an extension of the CIF format was phased in. mmCIF became the standard format ...
3-dimensional multiple sequence alignment, produced on the 1D-3D Group Alignment Viewer, by RCSB Protein Data Bank. 3D visualization – A common, one-dimensional, representation of a protein sequence is a list of the amino acids that form it. However, 3-dimensional alignment displays the way sequences may match each other.
The database of three-dimensional interacting domains (3did) is a biological database containing a catalogue of protein-protein interactions for which a high-resolution 3D structure is known.

PIR was established in 1984 by the National Biomedical Research Foundation as a resource to assist researchers and customers in the identification and interpretation of protein sequence information. Prior to that, the foundation compiled the first comprehensive collection of macromolecular sequences in the Atlas of Protein Sequence and ...
The chemical structure of DNA is insufficient to understand the complexity of the 3D structures of DNA. In contrast, animated molecular models allow one to visually explore the three-dimensional (3D) structure of DNA. The DNA model shown (far right) is a space-filling, or CPK, model of the DNA double helix. Animated molecular models, such as ...
The extensible NEXUS file format is widely used in phylogenetics, evolutionary biology, and bioinformatics. It stores information about taxa , morphological character states, DNA and protein sequence alignments, distances, and phylogenetic trees. [ 1 ]
