Figure 1
The BgaR dimer bound to lactose. The image on the left depicts the dimer as a cartoon coloured as a Jones' rainbow from the N-terminus to the C-terminus. Lactose is shown as a stick model with C atoms in green. The image on the right is an approximate 90° rotation and the colours have been changed to highlight the secondary structure (β-strands in magenta and α-helices in cyan). Lactose is shown as a stick model with C atoms in green. The dimer is held together by the long C-terminal helices and the saccharide-binding site is between the β-sheets of the jelly-roll fold.
