Polypeptides tend to become organized independently into a variety of functional scaffolds and to socialize with other partner molecules, forming small biomolecular complexes or large assemblies, in various intersections of biological pathways. Proteins’ architecture, plasticity and interaction determine the fate of a variety of biological events. Understanding the functional role of peptides and proteins is strongly coupled to the atomic-level insights of their structure and flexibility.
The research activities of the group encompass the study of the structure and dynamics of peptides and proteins involved in signalling pathways, proteolysis and ion/metal transfer, both in silico and in vitro.

Terra Vitro

Terra Vitro is the wet biology lab for protein production, labelling, purification and characterization. NMR study of proteins and protein complexes requires the production and isolation of the molecules labelled in 13C and 15N active NMR nuclei. Proteins with a molecular weight ranging from 8 to 22 kDa (70 to 200 amino acids) are currently over-expressed in high yields in our lab using bacterial and eukaryotic systems and purified/isolated accordingly.
The lab offers a variety of expression vectors and is equipped with all the appropriate facilities for expression, purification and analysis of recombinant native or mutated proteins, bearing a variety of purification tags.

Terra Silico

Terra Silico is the computer lab for NMR data analysis and Biomolecular Simulations. NMR data provide an atomic-level information for the structure, dynamics, and interaction of polypeptides and can drive Structure-Activity Relationship studies through the design of protein/peptide analogues or protein substrates. Biomolecular Simulations are applied to study the conformational dynamics of protein-protein /peptide /substrate complexes.

Terra silico is equipped with powerful computational systems running software for NMR data analysis, structure calculations, docking and molecular dynamics simulation, structure validation etc.


grnmrAn NMR-related site presenting the Greek groups and their activities in the field. There is a number of teams in various universities and institutes that are applying NMR spectroscopy for conformational studies and for analytical purposes. NMR instruments are settled down in Universities of Athens, Thessaloniki, Ioannina, Crete and Patras, as well as research institutes at Athens (NCSR Demokritos, National Hellenic Research Foundation; NHRF) with the higher field magnet being 600 MHz (U of Athens and NHRF). The research activities of the Greek NMRgroups are oriented to the analysis of natural products and drug candidates, the conformational properties of peptides and proteins and food quality analysis. The 1st National Greek NMR Meeting was held, as a Post-Symposium event to 18th Euro QSAR. For information about the roadmap of the BioNMR community in Greece, as resulted by this meeting, and to get the material of the meeting follow the link Read more...


EAST-NMR is an FP7 EU-funded project. It has the specific aim to enhance the access to NMR facilities and the NMR services to East European users towards an efficient and coordinated pan-European pool of NMR capacities to enable collaborative research and technological achievements.
EAST-NMR will combine activities, such as: (i) Networking, (ii) Trans-national access, and (iii) Joint research activities, in a co-ordinated manner. University of Patras is the Greek partner (Partner #12) to EAST-NMR project and is participating to a variety of activities such as, NMR workshops & conferences, young investigators meetings, etc. The program website will be available soon and will be announced.


"SEE-DRUG" is a NMR-oriented FP7-REGPOT project (Coordinator: G.A. Spyroulias) that was attributed to a group of research teams from UPAT (Depts of Pharmacy, Medicine, Chemistry & Biology) for their excellence in the field of Structural Biology. The project aims to upgrade the Structural Biology capacities of UPAT and to the Establishment of a Center of Excellence for Structure-Based Drug Design efforts in South-Eastern EU region. Through this grant it is anticipated the installation of a high-field 700 MHz, NMR instrument in 2012, optimized for Biomolecular NMR applications. This instrument will be the highest NMR field in Greece, and one of the highest in the entire Eastern EU region. The research Capacities of UPAT will be considerably upgraded and new collaborative links will be established among Greek or EU researchers and industrial stakeholders. For more information please visit the SEE-DRUG web page Read more...


Research Highlights

Modelling and NMR studies of Cys-loop receptors ("FP7-Neurocypres") to gain new insights for the structure, dynamics and interaction of Ligand-gated ion channels (LGICs), such as AChR & homologues {Dimitropoulos N. et al. 2011, Chasapis C.T. et al. 2011}.

NMR-driven Structure-Activity studies of proteins involved in Ubiquitination pathway, like Arkadia E3 ubiquitin ligase RING domain {Kandias N. et al. BBRC 2009, Chasapis C.T. et al. 2011}, a positive regulator of TGF-β family signaling.

Conformational Dynamics of Zn-proteases through Computational approaches and NMR studies to investigate the structural basis of the enzyme-substrate binding and selectivity (Angiotensin-I Converting Enzyme (ACE), Anthrax Lethal Factor (ALF) etc.; Dalkas G. et al. 2010, Dimitropoulos N. et al. 2010, Dalkas G. et al. 2009, Papakyriakou A. et al. Biochemistry 2007}.
