TATA boxes are common structural features of eucaryal class II and archaeal promoters. In addition, a gene encoding a polypeptide with sequence similarity to eucaryal TATA-binding protein (TBP) has recently been detected in Archaea, but its relationship to the archaeal transcription factors A (aTFA) and B (aTFB) was unclear. Here, we demonstrate that yeast and human TBP can substitute for aTFB in a Methanococcus-derived archaeal cell-free transcription system. Template-commitment studies show that eucaryal TBP is stably sequestered at the archaeal promoter and that this interaction is further stabilized in combination with aTFA. Binding studies revealed that recognition of an archaeal promoter by TBP involves specific binding to the TATA box. These findings demonstrate a common function of TBP and aTFB and imply a common evolutionary origin of eucaryal and archaeal transcriptional machinery.
