Archaeal transcription factor B
Archaeal transcription factor B (TFB), homolog of eukaryotic TFIIB and bacterial sigma factors, binds the BRE upstream of the TATA box with TBP and recruits archaeal RNA polymerase; many archaea encode multiple TFB isoforms.
Transcription factor II B
Transcription factor II B (TFIIB) is a eukaryotic general transcription factor that bridges TBP-bound promoters to RNA polymerase II, binds BRE promoter elements, selects transcription start sites, and is conserved in archaea and Pol I/III systems.
