    A complex of two TFIID TATA box-binding protein-associated factors (TA FIIs) is described at 2.0A resolution. The amino-terminal portions of dTAFII42 and dTAFII62 from Drosophila adopt the canonical histone fold, consisting of two short alpha-helices flanking a long central alpha-helix. Like histones H3 and H4, dTAFII42 and dTAFII62 form an intimate heterodimer by extensive hydrophobic contacts between the paired molecules. In solution and in the crystalline state, the dTAFII42/dTAFII62 complex exists as a heterotetramer, resembling the (H3/H4)2 heterotetrameric core of the histone octamer, suggesting that TFIID contains a histone octamer-like substructure.
