FUNCTIONAL CHARACTERISATION OF SULFURTRANSFERASE PROTEINS IN HIGHER PLANTS von der Naturwissenschaftlichen Fakultät der Gottfried Wilhelm Leibniz Universität Hannover zur Erlangung des Grades Doktor der Naturwissenschaften Dr. rer. nat. genehmigte Dissertation von Dipl.-Biol. Andrea Bartels geboren am 21.01.1977 in Neustadt a. Rbge 2006 Referentin: PD Dr. Jutta Papenbrock Koreferent: Prof. Dr. Bernd Huchzermeyer Tag der Promotion : 14. Juli 2006 SUMMARY SUMMARY Sulfurtransferases (Str) catalyse the transfer of a sulfur atom from suitable sulfur donors to nucleophilic sulfur acceptors. Str proteins are present in organisms of all three phyla but although several functions were proposed, their biological role is yet to be determined. The research aims at the elucidation of the properties and functional relevance in vivo of the 20 members of the heterogeneous Str multi protein family in Arabidopsis thaliana. The 20 putative Str proteins, each containing at least one rhodanese (Rhd) domain, have been classified into six groups according to sequence homologies.
