Chemical Component Search Tools
Use the forms below to search for chemical components within the PDB Component Dictionary.
Your query results are also searchable!
- Search for chemical components by 3-letter component
identifier code, molecular name, molecular formula, SMILES description,
or InChi/InChiKey chemical description.
You can also check to see if a 3-letter code is being held by a deposition in progress.
- Chemical substructure searches can also be conducted by starting from a chemical drawing created within the MarvinSketch tool.
Either start with a SMILES description or chemical data file (see
drop-menu for acceptable formats), or draw a 2D chemical structure from
scratch (Launch without input). It can also generate chemical component definitions from your 2D structure.
- Search for instances of a chemical component throughout the PDB. The Display option allows you to simply see a list of PDB codes, or to download these coordinates in PDB, MOL/SDF and mmCIF formats.
- You can also search for analogs to the standard amino acids,
nucleotides, popular drugs, and common aromatic ring systems by using
the Browse feature in the top menu bar.
Each hit from your
initial query will contain links to continue searching by similar name,
chemical formula, or structure (SMILES).
