Twelve structures of distinct members of the lipocalin protein family have
been solved experimentally. These structures have revolutionised our unders
tanding of the properties of the lipocalins. Many more members of the famil
y have been crystallised and now await structure solution. The number of so
lved lipocalin structures is steadily increasing, and with it increases our
knowledge of this enigmatic and challenging protein family. (C) 2000 Elsev
