Description:
β-lactoglobulin is the major whey protein of cow's milk (~3 g/l), and is also present in many other mammalian species; a notable exception being humans. Its structure, properties and biological role have been reviewed many times.
Folding intermediates for this protein can be studied using light spectroscopy and denaturant. Such experiments interestingly show an unusual but important intermediate composed purely of alpha helices, despite the fact that the native structure is beta sheet. Evolution has probably selected for the helical intermediate to avoid aggregation during the folding process.
