Post-doc position at IST Austria: deciphering the structural and dynamical basis of allosteric enzymes by NMR

Post-doc position in the Schanda group at IST Austria: deciphering the structural and dynamical basis of allosteric enzymes


The project

What is the mechanistic basis for long-range communication in allosteric proteins? And how, along evolution, did proteins acquire the capacity to be allosterically regulated?

We study these questions with an integrated approach that combines state-of-the-art NMR approaches, both in solution and in the solid state, with a host of biophysical methods, simulations and functional assays. The family of proteins we study are large (>120 kDa) and we have successfully established functional and dynamical studies of several such large machineries at the atomic level.

A success of the project is when we will understand what are the structural and dynamical events that enable allosteric communication, and what it is that makes the non-allosteric proteins of this family behave differently. We will characterise dynamics on multiple time scales and characterise short-lived states and their role for allostery and enzymatic function.

The proteins we study are generally considered rather challenging due to their size. Building upon several successful cases from our group, we will overcome these challenges by several approaches. We have available several ways of getting specific isotope labels in strategic positions in otherwise deuterated proteins (including yet unpublished ones); these methods provide high resolution even in solution-NMR despite the protein size. Moreover, we use magic-angle spinning NMR to gain access to essentially all atoms, independent of the size. Specific labelling also helps there, as it supports the precise determination of dynamics.

In this particular project, we will combine these techniques with high-pressure NMR, thereby characterising how pressure activates proteins of organisms living in the deep sea. Together with other proteins, mesophilic or thermophilic, we will build an understanding of the crucial elements that make proteins allosteric or non-allosteric, including the activation of the allosteric capacity.



Successful candidates shall have a PhD degree in biochemistry or biophysics, and ideally experience in NMR spectroscopy applied to biomolecules. A strong background in structural biology and protein production and/or bio-NMR methods development is expected.

We expect candidates to enjoy creative and critical thinking, possess a strong motivation to learn new techniques, solve puzzling questions, and overcome technical challenges. We are a small international team and we look forward to working with a team player who is eager to take responsibility for their project and genuine interest in the group’s work.

We are aware that most candidates will not have experience in all aspects, from MAS NMR to solution- (& pressure-) NMR to biochemistry, and we expect a strong dedication to learning and acquiring new skills of use for this project and the further career.


The environment we offer

Our group is located at IST Austria, at the outskirts of Vienna, one of the cities with highest quality of life according to many rankings. The group was established at ISTA in 2021, and we currently have 9 members from 7 different countries. English is the institute language.

We have access to three brand-new spectrometers (600, 700 and 800 MHz + soon a 400), equipped with either solution-state cryoprobes or MAS NMR probes (0.7 mm to 3.2 mm). We furthermore have access to a state-of-the-art cryo-EM facility and various techniques for protein production and characterisation.

Our institute is rapidly growing, and you will have the chance to be exposed to a wide range of research areas (with many joint seminars), and with several new faculty joining our structural biology programme in 2024, you will have a chance to connect to a community including cryo-EM, electron tomography, machine learning, protein design, many groups working in developmental, cellular and molecular biology,… We believe it is a highly stimulating environment for a young researcher on an academic career track.


The post-doc contract can be up to 5 years, allowing candidates to develop not only their skills but also prepare for positioning themselves on their way to an academic career.


How to apply:

Please send your appliction, including

* a detailed letter that describes your background and motivations/reasons for applying as well as your vision for your research, for your postdoc period and beyond,

* your publication record, possibly your experience in supervision of students, presentations,…; ideally complement this by stating what it is that you are particularly proud of,

* names of 2-3 references
