The basic aspects of ligand-protein interaction may be summarized under the term 'molecular recognition' and concern the specificity as well as stability of ligand binding. Molecular recognition is thus a central topic in the development of active substances, since stability and specificity determine whether a substance can be used as a drug. Nowadays, computer-aided prediction and intelligent molecular design make a large contributioMethods and Principles in Medicinal ChemistryLigand binding (Biochemistry)BiochemistryLigand binding (Biochemistry)Biochemistry.572.33615.19615/.19Böhm Hans-Joachim1606758Schneider Gisbert1965-855861MiAaPQMiAaPQMiAaPQBOOK9910829879503321Protein-ligand interactions from molecular recognition to drug design4106565UNINA
