NCBI Structure Group

The NCBI Structure Group maintains: MMDB, a database of macromolecular 3D structures, as well as tools for their visualization and comparative analysis. MMDB, the Molecular Modelling DataBase, contains experimentally determined biopolymer structures obtained from the Protein Data Bank (PDB); PubVast, a database of structure-structure alignments; PubChem, a database of small molecules, which provides information on their biological activities; and CDD, the Conserved Domain Database, a protein annotation resource, which consists of a collection of well-annotated multiple sequence alignment models for ancient domains and full-length proteins.
