As you are looking at these structures yourself, notice that TATA-binding protein, even though it is composed of a single protein chain, is composed of two symmetrical halves. This symmetry is easily seen in the two pairs of phenylalanines and the two asparagines shown in the lower figure. It is thought that an ancient gene duplication created this protein by combining two copies of the same gene. | As you are looking at these structures yourself, notice that TATA-binding protein, even though it is composed of a single protein chain, is composed of two symmetrical halves.
