Cn3D

Cn3D is a visualization tool for biomolecular structures, sequences, and sequence alignments. With version 4, Cn3D is now a complete multiple alignment editor as well, and includes algorithms for aligning sequences to other sequences and to structures. Cn3D is typically run from a WWW browser as a helper application for NCBI's Entrez system, but it can also be used as a standalone application. Cn3D does not read PDB-format files directly, but instead uses open in new windowNCBI's MMDB database.
