Short resume

Research focus on X-ray crystallography, small-angle X-ray scattering (SAXS) and electron microscopy. Contributed to more than 50 entries to the Protein Data Bank. Research areas include:

Studied on ribosomal proteins and elongation factor structure and function: Worked on 3D structures of elongation factor G (EF-G), ribosomal recycling factor (RRF), ribosomal proteins L1, L22, S8, TL5 and some mutants and complexes of these.

Studies on heme synthesis and mechanisms of porphyrin metallation: Numerous X-ray structures of bacterial (Bacillus subtilis) and yeast ferrochelatase; X-ray and EM structures of magnesium chelatase.

Studies on iron homeostasis in mitochondria: X-ray structures of yeast frataxin, a mitochondrial protein involved in iron storage and detoxification, also known as a factor in the neurodegenerative disease Friedrich’s Ataxia. The X-ray structures of trimers of the protein and their complexes with various metals, single-particle electron microscopic structure of iron-free and iron-loaded 24-subunit oligomers. Small-angle X-ray scattering (SAXS) studies of metal-induced oligomerisation of frataxin. EM studies of complexes with ferrochelatase and with components of the Fe-S cluster synthesis machinery.

Studies of enzymes from the polyamine biosynthesis pathway: X-ray structures of C. elegans and Plasmodium falciparum spermidine synthase in complexes with substrates and inhibitors; X-ray structure structure of human ornithine decarboxylase inhibitor complex.
