Schematic of the inverted repeats of a transporter. (A) The topologies of the inverted repeats, boxed in blue and orange, are identical when inverted with respect to the plane of the membrane. The color lightness of the helices can be used to identify corresponding helices in the two repeats. (B) In any given state, the conformations of the repeats differ. When the IF conformations of the repeats are swapped, they form the OF state and vice versa.
