Q-BioLiP Statistics

1. Entries in Q-BioLiP

The Q-BioLiP data are organized into three categories: biologically relevant interactions; biologically irrelevant interactions; and structures with ligands or proteins only.

Among the total entries, 35% and 63% are annotated as biologically relevant interactions and biologically irrelevant interactions, respectively; the remaining 2% are structures with ligands or proteins only.

2. Interaction-based data (before 2026-01-02)

These protein-small molecules/metal ions/peptide/DNA/RNA interaction data are derived from biologically relevant interactions.

Type of interaction	Number of interactions	Number of unique receptors
Protein–small molecules interaction	560,724	172,762
Protein–metal ions interaction	321,287	87,291
Protein–peptide interaction	36,413	23,917
Protein–protein interaction	180,057	180,057
Protein–DNA interaction	12,088	10,369
Protein–RNA interaction	15,317	7,971
RNA–small molecules interaction	270,905	6,211
