Rational design of Type I secretion substrates


Area: expression
Project Start: 1.10.2009
Supervisor(s): Prof. Dr. Karl-Erich Jaeger, Prof. Dr. Lutz Schmitt, Prof. Dr. Sander Smits
University: Duesseldorf


Dr. Christian Schwarz received a fellowship from CLIB-GC from October 2009 until October 2012, when he graduated summa cum laude. He is currently a postdoctoral fellow at HHU Düsseldorf and is founding his own startup "pep2express".

During his thesis, Christian won second place in the innovation competition at Düsseldorf University in 2012.

Christian patented some of the results of his thesis in the following patent:
Agents and methods for the expression and secretion of peptides and proteins
(2011, EP11186225.6)
Patent holders: Christian Schwarz, Sander Smits, Lutz Schmitt
A general secretion system in E. coli for the production of heterologous polypeptides. Secretion levels reach up to 1 g/L. Secreted polypeptides are highly pure and feature the expected biological function.
