Location & approach

By car

The campus of Dortmund University of Technology is located near the Dortmund West motorway junction, where the A45 Sauerland route crosses the B1/A40 Ruhr expressway. The Dortmund-Eichlinghofen exit on the A45 motorway leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 motorway leads to the North Campus. The university is signposted at both exits.

By bus and train

The ‘Dortmund Universität’ S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund Central Station and in the opposite direction to Düsseldorf Central Station via Bochum, Essen and Duisburg. The university can also be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offers an interactive network map.

The H-Bahn

The H-Bahn is one of the landmarks of TU Dortmund University. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Centre via Campus South and Dortmund University S, while Line 2 runs every 5 minutes between Campus North and Campus South. It covers this route in two minutes.

By plane

From Dortmund Airport, you can take the AirportExpress to Dortmund Central Station in just over 20 minutes and from there take the S-Bahn to the university. Düsseldorf Airport, around 60 kilometers away, offers a wider range of international flight connections and can be reached directly by S-Bahn from the university station.

Plan of site & interactive map

The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".

Research Paper: Biocatalytic production of the antibiotic aurachin D in Escherichia coli

Biocatalytic production of the antibiotic aurachin D in E.Coli

A new scientific article has been published.

Abstract:

Aurachin D is a potent inhibitor of cytochrome bd oxidases, which are potential targets in the treatment of infectious diseases. In this study, our aim was to improve the biocatalytic production of aurachin D from a quinolone precursor molecule with recombinant Escherichia coli cells expressing the biosynthesis enzyme AuaA. In order to achieve a high-level production of this membrane-bound farnesyltransferase in E. coli, the expression of the auaA gene was translationally coupled to an upstream cistron in accordance with a bicistronic design (BCD) strategy. Screening of various BCD elements led to the identification of optimized auaA expression cassettes, which increased the aurachin D titer in E. coli up to 29-fold in comparison to T7-mediated expression. This titer could be further raised by codon optimization of auaA and by introducing the mevalonate pathway into the production strain. The latter measure was intended to improve the availability of farnesyl pyrophosphate, which is needed as a cosubstrate for the AuaA-catalyzed reaction. In sum, the described efforts resulted in a strain producing aurachin D with a titer that is 424 times higher than that obtained with the original, non-optimized expression host.
