Structural models of the two families of UndP membrane transporters from the AlphaFold Protein Structure Database. (A) Structural model of a UndP transporter of the DedA superfamily (UptA from B. subtilis). The model of the B. subtilis UptA (YngC) transporter has two membrane loops that re-enter the cytoplasmic lipid bilayer (in magenta); they are frequently found in membrane transporters. (B) Structural model of UndP transporter of the DUF368 superfamily (PopT from S. aureus). The model of S. aureus PopT (SAOUHSC_00846) also has two loops that re-enter the cytoplasmic membrane (in red).
