Figure 4: Structure with a slab ( approx-23
Å) of the transmembrane domain viewed from the periplasmic
side. The side chains of three functionally essential charged
residues—Asp 407, Asp 408 and Lys 940—and functionally
important residue Thr 978 are shown in a ball-and-stick
representation. Colours of the protomers are as in Fig. 1. Roman
numerals indicate the transmembrane helix numbers^13.
