RTPRTP
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 N-terminus end, first alpha helix (a1), unstructured loop that is equivalent to the first beta sheet (B1), helix loop helix structure (a2 - a3), 2 beta sheets with a connecting loop that makes up the 'wing' structure (B2 - B3) and an additional long alpha helix involved in dimerisation (a4).
Binding to B siteBinding to B site
The RTP binding site consists of a 30bp sequence consisting of two inperfect 16 bp repeats, the A site and the B site.
