Curriculum vitae

Full Professor at the University of Bologna since 2001, he carries out his research in the field of bio-inorganic chemistry and chemistry of metal ions in biological systems, with the aim to elucidate their role in biomolecules. His research curriculum reflects an evolution from basic physical, coordination and organometallic chemistry to bioinorganic chemistry. This evolution has allowed him to build on chemical grounds a level and breadth of knowledge extremely useful to understand the role of metals in biological processes. Furthermore, the application of a large variety of physical methods to model compounds has been a learning bench for further applications of the same techniques to more complex biomolecules. Since he became an independent scientist, his main interest has been focused on the chemistry of metal ions in biological systems. The research carried out is oriented science applied to the chemical processes occurring in the environmental and human biosphere, with potential impact in the biomedical and agro-environmental fields.

In recent years, his research activity has focused on the study of the structure and function of urease, a Ni(II)-dependent enzyme that plays a key role for potential applications is biomedical and agricultural biotechnology. In particular, the structure of the enzyme bound to several inhibitors has been determined using protein crystallography, and the catalytic mechanism has been elucidated. Moreover, the molecular bases of urease activation by Ni(II) insertion in the active site have been established by the study of accessory proteins responsible for the intracellular trafficking of this essential but also toxic metal ion, while the structure and function of Ni(II)-dependent transcription factors that regulate the genes that code for proteins acting in the sensing and metal-homeostasis have also been investigated.

In general, the metal-containing biomolecules are obtained from natural sources or using recombinant DNA technology, and their molecular structure and function are established, clarifying the reciprocal influence of the metal ions and the protein matrix as well as the interaction modes of the metallo-protein with substrates, inhibitors, and other biological substrates such as proteins and DNA. These goals are pursued using a structural biology approach, applying high resolution NMR spectroscopy, biocrystallography, and other techniques such as X-ray absorption spectroscopy, circular dichroism, fluorescence spectroscopy, bioelectrochemistry, light-scattering, and calorimetry. A significant branch of the research is dedicated to the application of computational methods and biomolecular structural modeling to the elucidation of structures and reaction mechanisms.


Stefano Ciurli received his Laurea cum laude in Chemistry, inorganic/physical chemistry major, at the University of Pisa (1986) with a research carried out at the Department of Chemistry of Columbia University (New York, NY, USA) under the supervision of Prof. Carlo Floriani. The thesis focused on the functionalization of late transition metal (Fe, Co, Ni, Cu) porphyrino-type complexes, to study low oxidation states of the metals in ionic pairs with alkali ions. In addition, the synthesis of complexes of early transition metals (Ti, Zr, V, Nb) with highly sterically flexible macrocycles to obtain cis-coordination sites available for catalysis was also carried out.

He then moved to the Department of Chemistry at Harvard University (Cambridge, MA, USA) to carry out graduate research under the supervision of Prof. Richard H. Holm, focused on the synthesis of subsite-differentiated cubane-type clusters of the type MFe3S4 (M=Fe, V, Mo, Re, Co, and Ni) as models for similar centers in metallo-proteins and metallo-enzymes. The structures and properties of the obtained compounds were studied using IR, UV-vis, Mössbauer, EPR, X-ray absorption and NMR spectroscopies, while the structures of the compounds were obtained using small molecules X-ray crystallography. Electrochemical techniques such as cyclic voltammetry, differential pulse polarography and coulometry were routinely used, while magnetic susceptibility measurements were carried out using SQUID magnetometers at the Massachusetts Institute of Technology. He received a Ph.D. in Chemistry from Harvard University in 1990.

He then carried out post-doctoral work from 1990 to 1992 under the supervision of Prof. Bertini (University of Firenze) and Prof. Luchinat (University of Bologna). During this time, he became acquainted with the purification of metalloproteins containing FeS clusters from natural sources such as bacteria and plants. The goal of the research was the elucidation of the relationships between structural, functional, and spectroscopic parameters in iron-sulfur proteins. The main technique used was paramagnetic NMR spectroscopy of iron-sulfur proteins. Acquaintance was gained on theoretical models of magnetic exchange and molecular mechanics and dynamics of iron-sulfur proteins.
