Retrieves protein information (inluding sequences and annotations) from a variety of sources, including SwissProt, PIR, PRF, PDB, and translations from annotated coding regions in GenBank and RefSeq.
General purpose multiple sequence alignment program for DNA or proteins. It produces multiple sequence alignments of divergent sequences and calculates the best match for the selected sequences, and lines them up so that the identities, similarities and differences can be seen.
Encyclopedia on the structure and function of proteins, RNA, DNA, and other macromolecules, and their assemblies and interactions with small molecules.
Repository of information about the 3D structures of large biological molecules, including proteins and nucleic acids, and their relationships to sequence, function, and disease.
