GenBank is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences. It is part of the International Nucleotide Sequence Database Collaboration, which is comprised of the DNA DataBank of Japan (DDBJ), the European Molecular Biology Laboratory (EMBL), and GenBank at NCBI.”
This database specializes in immunoglobulins (Ig), T-cell receptors (TcR) and major histocompatibility complex (MHC) molecules of vertebrate species. A tool, IMGT/DNAPLOT, allows Ig, TcR and MHC sequence analysis.
“The database provides a catalogue and structure-based classification of peptidases (i.e. all proteolytic enzymes). This is a large group of proteins (nearly 2% of all gene products) that is of particular importance in medicine and biotechnology.”
“The single international repository for the processing and distribution of 3-D macromolecular structure data primarily determined experimentally by X-ray crystallography and NMR.” The PDB includes 10132 coordinate entries, 9422 proteins, 698 nucleic acids, and12 carbohydrates. RCSB is Research Collaboratory for Structural Bioinformatics.
