RTP is a DNA binding protein from Bacillus Subtilis that uses a helix-loop-helix binding motif. In solution it shows a symmetric structure typical of the winged helix loop helix family, with an unstructured end, first alpha helix , unstructured loop that is equivalent to the first beta sheet (B1), helix loop helix structure (-), 2 beta sheets with a connecting loop that makes up the 'wing' structure and an additional long alpha helix involved in dimerisation .
The RTP binding site consists of a 30bp sequence consisting of two inperfect 16 bp repeats, the A site and the B site.
