The response regulator Spo0A is comprised of a phophoacceptor domain and a transcription activation domain. This domain corresponds to the transcription activation domain and forms an alpha helical structure comprising of 6 alpha helices. The structure contains a helix-turn-helix and binds DNA [1][2].
