What are the applications of predicting the structure of proteins?
Just off the top of my head, protein structure is very important for determining how proteins interact, for example determining molecular pathways or viral capsid structures. Knowing the structure of a protein can help scientists better understand what it does and how it does it. By looking at protein structures, scientists can determine exactly how a different allele for a gene causes changes in an organism's phenotype at a biochemical level. Predicting sites within a protein's structure that have an enzymatic function allows scientists to predict how various factors effect it's function. Differences in temperature or pH can have an effect on protein structure as well, and understanding how a proteins changes based on pH or temperature changes can help scientists determine how a protein functions in its specific environment.
