Link	Description
BioLiP_nr.txt.gz	Annotations for each ligand-protein interaction site (readme)
protein_nr.fasta.gz	Protein receptor sequences clustered with 90% identity cutoff
dna_nr.fasta.gz	DNA ligand sequences clustered with 100% identity cutoff
rna_nr.fasta.gz	RNA ligand sequences clustered with 100% identity cutoff
peptide_nr.fasta.gz	Peptide ligand sequences clustered with 100% identity cutoff

All sequences are converted from residues with experimentally determined coordinates in the structure; residues unobserved in the structure are excluded.
