Protein Binding Affinity Analyzer

The Protein Binding Affinity Analyzer is a sophisticated bioinformatics tool that calculates binding affinity between proteins and small molecule ligands. Users can input protein sequences (in FASTA format), ligand structures (as SMILES strings), and experimental conditions (temperature, pH, ionic strength) to obtain accurate predictions of dissociation constants (KD), binding free energy (ΔG), and interaction analysis. The tool uses established bioinformatics algorithms including molecular mechanics and empirical scoring functions to provide reliable affinity predictions for drug discovery and biochemical research.
