Chemical Recognition in Biology formatIsbn:Softcover 9783642815058 major advances in our understanding formatIsbn:Softcover 9789402404937 major advances in our understanding of chemokine biology have led to chemokine receptors becoming specific therapeutic targets with great potential rts gegangen but may result from a progressive adaptation during which the initial struc tures of the enzyme and the ligand are modified (induced flt mechanism) They led to a rather static representation of the recognition process illustrated by the lock and key model that still continues to influence our overall image of recognition and its specificity
