The beta-strands form a single anti-parallel beta-sheet and the three alpha-helices pack side-by-side onto one surface of the beta-sheet. In this architecture, the domain's hydrophobic core is at the sheet-helix interface, and the second surface of the beta-sheet is completely exposed. The domain is a DNA-binding motif, with a consensus sequence containing nine base pairs (5'-TTTGCTTTA-3'), that appears to bind to various mot boxes, allowing access to the minor groove towards the 5'-end of this sequence and the major groove towards the 3'-end [1].
