Anne Houdusse, head of the Structural Motility Team, CNRS/Institute Curie, Paris, France, is the winner of this years Women in Science Award given by The European Molecular Biology Organization (EMBO) and the Federation of European Biochemical Societies (FEBS). Nominally a structural biologist her work focuses on the chemistry, i.e. the molecular mechanism of action, of myosins. Houdusse clarified the molecular structure and function of the muscle-contracting proteins as well as motility processes within cells. Her atomic resolution structures provided pioneering functional insights into the movement of molecular motors during muscle contraction.
