Cytoskeleton in Mycoplasma pneumoniae

























Referees: Prof. Dr. Richard Herrmann
Prof. Dr. Claus Hobe Schröder Acknowledgments

This thesis has been accomplished at the Zentrum für Molekulare Biologie Heidelberg (ZMBH),
Ruperto-Carola University, Heidelberg, under the supervision of Prof. Richard Herrmann.

First of all, I would like to especially express my sincere gratitude to Prof. Richard
Herrmann for giving me the opportunity to work in his research group and for his
supervision throughout my PhD years, as well as for his interest, thoughtful discussions,
patience and solicitude.

Furthermore, I would like to thank:
- Prof. Claus Hobe Schröder for his worthful comments as the second referee;
- Dr. Diana Hofmann for assistance with the 2-D gel electrophoresis and warmhearted
advice during the thesis writing process;
- Elsbeth Pirkl for help in solving many problems in the daily laboratory work;
- Katrin Tagscherer for providing very useful data concerning the synthesis of recombinant
HMW2-s;
- Armin Bosserhoff and Dr. Thomas Ruppert for mass spectrometric analyses of HMW2-s
and components of the subfractions from TAP-tag purification;
- Dr. Carl-Ulrich Zimmerman for useful suggestions in many experimental approaches;
- Dr. Jan Hegermann for collaboration in eletron microscopy of M. pneumoniae;
- Dr. Manfred Koegl for introduction into the two-hybrid system and important comments;
- Werner Schaller for colaboration in two-hybrid screens;
- Dr. Jörg Regula, Dr. Barbara Ueberle , Dr. January Weiner III and Dr. Ina Catrein, for
valuable discussions;
- Michael Schulz, Peter Pechel and all lab members for providing a good working atmosphere.

I am grateful to all the people of the ZMBH who helped me during my thesis work.

Finally, I am thankful to my family and friends for their incessant support and encouragement.
