β-Lactoglobulin – a three-dimensional perspective

Summary Bovine β-lactoglobulin has been the subject of intense study over the past 60 years by, effectively, every available physicochemical technique, of which one of the most powerful is X-ray crystallography. We present a short review of the X-ray crystallographic work on milk protein together with an overview of the properties as they are seen from the current state of crystallographic analyses. At the present time, structural analyses do not provide any further insights into the possible function of the protein.
