Subunit collapse upon release from the chaperone


 

Anton Zavialov's Home@Work Page

Research
My research is primarily focused on understanding mechanisms of action of molecular chaperones, proteins that assist the non-covalent folding/unfolding and the assembly/disassembly of other macromolecular structures. The mechanisms are revealed by determining conformational and energetic changes both in chaperones and substrate proteins during the chaperone assisted folding and assembly. In addition, I perform more “traditional” structure-function studies of a family of surface organelles of Gram negative pathogens (e.g. Yersinia and Salmonella spp), which we call “polyadhesins assembled via the FGL chaperone-usher pathway”, a novel family of extracellular signaling proteins, the adenosine deaminase related growth factors (ADGF), and a family of cystein proteases, the metacaspases, which are involved in the programmed cell death in plants.


Funding
Our studies are supported by grants from the Swedish Research Council (Natural Science and Medicine) and the Swedish Research Council for Environment, Agricultural Sciences and Spatial Planning (FORMAS).
