Type I and Type II interactions at the inner membrane. (A) The Type I RNA domain (L-I) binds to the cognate site R-I, leading to its transfer (blue arrow) and to positive regulation (green arrow) of the Type II site (R-II). The latter interaction results in binding of the Type II domain (L-II). Type II RNA is subsequently transferred (blue arrow) and also negatively regulates site R-I (red arrow). (B) The Type I and Type II domains are part of the same molecule. Sequential or simultaneous positive and negative effects occur on binding sites R-I and R-II.
