Dear all
Is there any database available that has only natural ligands in PDB? I came across - NLDB -natural ligand db, but there seems to be no option for download, neither is there a list of all natural ligands used.
Also databases like KEGG Reaction (compounds) have a problem of mapping the KEGG IDs to PDBIDs and much of the information is lost.
Could you pls. suggest any downloadable natural ligand DB
