Protein folding, stability and design true Protein folding beta12orEarlier Protein residue interactions Protein design Protein stability, folding (in 3D space) and protein sequence-structure-function relationships. This includes for example study of inter-atomic or inter-residue interactions in protein (3D) structures, the effect of mutation, and the design of proteins with specific properties, typically by designing changes (via site-directed mutagenesis) to an existing protein.
