Recently the definition of the metazoan RNA polymerase II and archaeal core promoters has been expanded to include a region immediately upstream of the TATA box called the B recognition element (BRE), so named because eukaryal transcription factor TFIIB and its archaeal orthologue TFB interact with the element in a sequence-specific manner. Here we present the 2.4-A crystal structure of archaeal TBP and the C-terminal core of TFB (TFB(c)) in a complex with an extended TATA-box-containing promoter that provides a detailed picture of the stereospecific interactions between the BRE and a helix-turn-helix motif in the C-terminal cyclin repeat of TFB(c). This interaction is important in determining the level of basal transcription and explicitly defines the direction of transcription.
