Crystallography protein
WebProteins consist of an elaborate arrangement of interior folds that collapse into a final thermodynamically stable structure and, for many proteins, only a modest free-energy gain (generally only −3 to −7 kcal/mol) (Lindquist and Kelly, 2011) is associated with correct folding of a protein compared with its innumerable potential misfolded ... WebJan 30, 2008 · The most widely used method of crystallization is vapor diffusion. The protein solution is either a hanging or sitting drop that equilibrates against a reservoir containing crystallizing agents...
