In the period of 27th – 30th June 2017, Prof. Dr. Cecilia Rokusek, Ed.D., M.Sc., R.D., Provost and Vice-president for international relations, Larkin University, Miami, Florida, visited the Center for Nanobiology and Structural Biology CAS in Nové Hrady, where she met the Center’s Director Prof. Rüdiger Ettrich, Ph.D.  He showed her how the Center works and introduced the C4Sys infrastructure, its development and the services offered. They discussed the possibility of education stays / internships of the Larkin university students at Nové Hrady as well as using the infrastructure by the students.

Prof. Rokusek subsequently visited the grounds of the University of South Bohemia in České Budějovice, where she was warmly welcomed by the former rector Prof. Libor Grubhoffer.



On Tuesday 20th June 2017 at 2 p.m., the seminar “Purification, Characterization, and Clinical Significances of Methionine Gamma Lyase Deaminase (Mgld) from Porphyromonas gingivalis” given by Dr. K.V. Venkatachalam, PhD. took place at the cinema auditorium of the Institute of Microbiology, CAS.  Prague – Krč.

Dr. Venkatachalam is a Professor of Biochemistry at the College of Allopathic Medicine, Nova Southeastern University, Ft. Lauderdale, Florida, where he has been active since 1999. His current research focuses on Methionine gamma lyase of Methionine metabolism and its impact on halitosis and cancer research.

After the seminar, he discussed the possibility of potential cooperation in the area of systems biology as well as regarding research infrastructures with the Institute of Microbiology’s scientists involved in the C4Sys infrastructure.



On Thursday 25th May 2017, the Center for Nanobiology and Structual Biology (CNSB) in Nové Hrady welcomed 48 students and their teachers from the Anglo-Czech High School in České Budějovice, the C4sys Research Infrastructure (C4Sys RI) being the main topic of their excursion.

First the students attended a speech by the director of the CNSB and the C4Sys RI – Prof. Rüdiger Ettrich. He introduced the infrastructure, talking about its development, purpose and objectives. He then explained what each research group involved in the infrastructure is focused on and what their main activities are, illustratively accompanying his speech with slides from his PPT presentation to clarify some difficult processes for the students. Since the C4Sys infrastructure is directly linked to the Infrastructure for Systems Biology in Europe (ISBE), prof. Ettrich also covered its role and the link between these two infrastructures. In the end, he compared data storing in the USA and in Europe.

The theoretical part was followed by a tour of laboratories at the CNSB. The students were divided in two groups and viewed the research premises of the Center with commentaries by their two “tour guides” – Prof. Ettrich and Dr. Lazar. They could see the scientific work as well as all the equipment used, in particular the Laboratory of Cell Biology, which focuses on the development and applications of two-photon polarization microscopy and related advanced optical microscopy techniques, and the Laboratory of Structure and Function of Proteins, with its central research issue being the relationship between the structure and function of the proteins and their complexes.

Finally, the students paid a brief visit to the Algatech Centre in Třeboň, whose Laboratory of Photosynthesis under the supervision of Prof. Josef Komenda is also part of the C4Sys infrastructure.

The ISBE Management Team Meeeting chaired by prof. Roel van Driel took place in Amsterdam on 25th April 2017.

On behalf of the C4Sys infrastrucure, the meeting was attended by the MT member prof. Rüdiger Ettrich. First, the present status of the ISBE project was discussed, as well as its challenges and next steps. Then the ISBE – ELIXIR relationship was outlined along with a future relationship ISBE – FAIRDOM. Finally, the members of the Management Team focused on ISBE Light services (the aims, timeline, module modelling & theory, module teaching & education and module stewardship).

The new ISBE website will be online as of 1st July . It will contain (i) the portal for the three classes of ISBE Light services, (ii) user access rules, and (iii) general ISBE information transferred from the old ISBE-Project website. The latter site will be terminated. The URL will be linked through to the new ISBE website.



The first meeting Intergovernmental Working Group took place in Amsterdam on Tuesday 10th January 2017.

The meeting was organised with support of the BBSRC and NOW, who together co-chaired the Legal and Governance work package of the ISBE’s Preparatory Phase.  The meeting was attended by the representatives of national European funding organisations, including two representatives from the Czech Republic.

Following the completion of the ISBE Preparatory Phase in July 2015, the ISBE partners have started to build a sustainable European research infrastructure. Two parallel tracks are being followed:

1) acquire start-up funding doe the interim phase

2) establish an initial portfolio of web-based services that are labelled ISBE light in three ISBE domains:

  • Modelling &Theory
  • Stewardship of research assets
  • Education & Training

At the meeting, the current progress as well as the process and the time line of building the ISBE was discussed and plans and activities in the context of national investments, priorities and roadmaps were considered.

A postdoctoral position is immediately available in the group of  Prof. Rudiger Ettrich at the Center for Nanobiology and Structural Biology, Institute of Microbiology of the Czech Academy of Sciences, Nove Hrady, Czech Republic.

Job description:

The job involves the use of computational methods, combined bioinformatics and molecular dynamics approach on translocation systems. This project will contribute to the understanding of different aspects of structure and function of cation translocation systems. These systems are either interconnected in function or structurally related. Studied systems will include non-selective cation channels as well as potassium- or calcium selective translocation systems. The study  shall also contributes to a clearer understanding of he evolutionary relationship between the  different groups of cation translocation systems and the the results will deepen the theoretical understanding of mechanisms behind cation translocation provided by these systems.


The applicant must hold a Ph.D. degree in chemistry or physics. The applicant should also have solid experience with computational modeling of biomolecules and an overall strong motivation. The ability to work independently as well as to collaborate with an extended team of theoreticians and experimentalists is also crucial.

Applicants should send an e-mail containing their CV, motivation letter, brief summary of previous research, list of publications and names plus e-mail addresses of 2 references.

The Annual Summer school in molecular biophysics and systems biology is supported by the International Visegrad Fund, and jointly organized by the University of South Bohemia and the Center for Nanobiology and Structural Biology of the Institute of Microbiology, Academy of Sciences of the Czech Republic. In partnership with the University of Miskolc, Hungary, the University of Warsaw, Poland and Comenius University in Bratislava, Slovakia, the summer school gives the chance to Czech and foreign university students to work for a month with experienced scientists and tutors in internationally respected research teams. During their time in Nove Hrady the students do not only research but also participate in an excellent lecture series that gets them a broad view on cutting-edge methodologies and research.

The participating students had to pass a highly competitive selection procedure and got the chance to work in excellent fully-equipped laboratories on topics related to systems biology and molecular biophysics. At the end of summer school, the research teams present their results in a student conference, where the best presentation get awarded by the scientific committee. In the final ceremony awards and certificates are presented to all participants.

The summer school 2016 is attended by 17 distinguished students from Poland, Czech Republic, Hungary, Ukraine, Belarus, Bulgaria, and Russia. 10 students were sponsored by the Visegrad Fund and the additional seven were funded by the University of South Bohemia
