Figure 2.
Fig. 2. A ribbon representation of the overall structure of
E. coli SufC. The catalytic α/β domain is shown in green and
the α-helical domain in blue. The motifs conserved in
ABC-ATPases are depicted by different colors: Walker A motif,
red; Walker B motif, magenta; ABC signature motif, yellow;
Q-loop, orange; and D-loop, dark blue. The side chains of Lys152
and Glu171, which are involved in a salt bridge between the
catalytic and helical domains, are represented by stick models
in blue and magenta, respectively.
