text: Structural genomics takes advantage of completed genome sequences in several ways in order to determine protein structures.  The gene sequence of the target protein can also be compared to a known sequence and structural information can then be inferred from the known protein's structure. Structural genomics can be used to predict novel protein folds based on other structural data.  Structural genomics can also take modeling-based approach that relies on homology between the unknown protein and a solved protein structure.
