BLAST compares a sequence of DNA or amino acids to a massive database and returns information about how similar the sequences are.
The comparison of nucleotide or protein sequences from the same or different organisms is a very powerful tool in molecular biology. By finding similarities between sequences, scientists can infer the function […]
SCOP is a hierarchical classification of proteins. Top in the classification are large fold types and digging down leads to small group of similar proteins.
The site’s classification also produces some interesting statistics on the fold types of proteins which can be found on the site.
CATH is a protein structure classification database. The database is organized by Class, Architecture, Topology, and Homologous super-family.
For any given structure classified in the database, CATH gives you information on the structure and function of that protein. The evolutionary relationships involving the structure of interest and other proteins in the database can also […]
The Cambridge Structural Database is a crystallographic database of small molecules. The database offers many ways to search for molecules such as structure similarity, unit cell and journal reference.
