  • Title: Bioinformatics Approach for Understanding the Folding and Stability of Proteins using Residue-residue Contacts
  • Abstract: Proteins perform a variety of functions in living organisms. The structure of a protein provides the information about its function. The formation of secondary structures and the stable tertiary structure is dictated by the interactions between amino acid residues and with the surrounding medium. The knowledge about inter-residue interactions in protein structures is very helpful to understand the mechanism of protein folding and stability. In this talk, I briefly outline the structural organization of proteins and the major interactions that are stabilizing protein structures. On this line, I introduce the classification of inter-residue interactions into short, medium and long range based on a simple geometric approach. The features of these interactions in different structural classes of globular and membrane proteins and their applications to protein secondary structure prediction will be presented. Further, the relationship between inter-residue contacts and protein-folding rates will be highlighted. Moreover, the importance of inter-residue interactions in protein-folding kinetics and for understanding the stability of proteins will be discussed.
