Abstract
Birch pollinosis is one of the prevailing allergic diseases. In all, 5–20% of birch pollinotics mount IgE antibodies against the minor birch pollen allergen Bet v 4, a Ca2+-binding polcalcin. Due to IgE cross-reactivity among the polcalcins these patients are polysensitized to various plant pollens. Determination of the high-resolution structure of holo Bet v 4 by heteronuclear NMR spectroscopy reveals a canonical two EF-hand assembly in the open conformation with interhelical angles closely resembling holo calmodulin. The polcalcin- ...
