Abstact

This is the first study determining the three-dimensional structure of Phl p 5a which reveals a novel mechanism for high allergenic activity based on flexibly connected IgE-reactive domains which cross-link effector cell-bound IgE more efficiently than isolated rigid globular proteins. These findings may also form a basis for specific immunotherapy strategies.
