Cambridge Crystallographic Data Centre (small molecules)
RNA Characterization of Secondary Structure Motifs (RNA CoSSMos) database. This tool allows the systematic searching of
all catalogued three-dimensional nucleic acid PDB structures that contain secondary structure motifs such as mismatches,
(a)symmetric internal loops, hairpin loops, and bulge loops.
A web tool for genome-wide annotation of human SNPs. The current version, LS-SNP/PDB, provides
information useful for identifying amino-acid changing SNPs (nsSNPs) that are most likely to have
an impact on biological function.
Membrane Protein Data Bank
A relational database with select structural and functional information on membrane proteins and peptides
Collecting experimentally determined binding affinity data exclusively for all types of biomolecular complexes in the Protein Data Bank, including protein-small molecule, nucleic acid-small molecule, protein-protein, and protein-nucleic acid complexes.
Simple PDB search for students and educators
The Pfam database is a large collection of protein families, each represented by multiple sequence alignments and hidden Markov models.
