In recent years, the sequencing of the human genome has enabled researchers to understand the full complement of genes which define the blueprint of human life. The next challenge for researchers is to understand the role of the molecules that are encoded by the genes and carry out their instructions. Acting alone or in groups, proteins a-re the essential active constituents of cells and perform most of an o-rganism’s biological functions.
Understanding of proteins and their role in molecular machines rem-ains a huge challenge. Structural Biology addresses that challenge b-y focusing on deciphering the three-dimensional shape or “structure” of these molecules, as their structure is intrinsic to their function in t-he cell.
