Sequence alignment of internal repeats. (A) The primary structure of the TATA-box-binding protein. (B) An alignment of the sequences of the two repeats of the TATA-box-binding protein. The amino-terminal repeat is shown in red and the carboxyl-terminal repeat in blue. (C) Structure of the TATA-box-binding protein. The amino-terminal domain is shown in red and the carboxyl-terminal domain in blue.
