SWEET2 (IMAGE) Carnegie Institution for Science Caption On the top left is a side view of the two identical bacterial SemiSWEET units, which together form the transport pore shown on the top right. On the bottom left is a side view of the plant sugar transporter SWEET2, in which the two units were fused via an additional helix (#4) to form a similar pore as in the SemiSWEET dimer from only a single protein, as shown in the bottom right.
