2.A.123.1.18
SWEET2b sugar transporter. Sequesters sugars in root vacuoles.  The 3-d structure is known. The subunit consists of two asymetic triple helix bundles (TMSs 1-3 and 5-7) connected by TMS4. SWEET2b is in an apparent inward (cytosolic) open state forming homomeric trimers. TMS4 tightly interacts with the first triple-helix bundle within a protomer and mediates key contacts among protomers (Tao et al. 2015).
