Protein sites · the orbital layer on a motif or a bound ligand, in the protein's own frame

Structure
MolNFT collections: PDB Bank (v2, BinaryCIF on chain), PDB (v1) and AlphaFold (v1). AlphaFold models have no metals; the zinc is then placed from the motif.
PDB, PDBx/mmCIF or BinaryCIF, plain or gzip-compressed, up to 20 MB. Only the first model is read. The file is sent once; later requests name it by its SHA-256.
All from the PDB. 5A7U is the ADR1a zinc finger inside the ribosome tunnel (cryo-EM at 4.8 Å, with the NMR model 2ADR docked into it); 7DDO is ACE2 (cryo-EM at 3.4 Å). The other three open on a bound ligand; in 19HC every haem is bonded to two cysteines (haem c).

Find structures by ligand · GL1X ligand index
Search the ligands of every MolNFT record.
The index and the records are GL1X's; this page reads them in your browser. A binding site opens its record here, on that ligand.
